Adding Up Transformer Output


Adding Up Transformer Output 1

As Dwayne Reid said above, this is impossible. From his answer, you can not expect to get more power out than you have available.As for the transformers themselves, other than the fact that it does not make sense that only one transformer gets power at a time, you can not combine a step up and step down transformer to any useful effect. Consider this, power must be conserved, thus if you start with 25V and 5A, you can step down to 2.5V and 50A (with an ideal transformer), or up to 250V and .5A.

In all these cases, you have both an input and output of 125W. Additionally, combining the effects of the transformers would give you your input back! You would step the voltage up, then lower it to its initial state.If you want to get 250V, you can do so with a 1:10 transformer.

It would step up your voltage to the required 250V. If you want 20A, you can do so with a 4:1 transformer, which would step down your voltage to 6.25V, but with 20A sourcing capabilities.If you want both 250V and 20A, you should consider how extraordinarily dangerous that is, and get a power supply rated to produce that. You can not combine two transformers to do this.

what is the difference between 2 ohms or 4 ohms?

Impedance The resistance offered by an electric circuit to the flow of alternating current - measured in ohms. A subwoofer rated at 2-ohm impedance will produce more output than a 4-ohm subwoofer, given similar input wattage, because the resistance is lower.

Ohm The unit of measurement for impedance or resistance. It tells you how much a device will resist the flow of current. If you take two signals of exactly the same strength and send one to a 4-ohm speaker and the other to an 8-ohm speaker, twice as much current will flow through the 4-ohm speaker.

In other words, the 8-ohm speaker will require twice as much power (wattage) to play at the same volume. Resistance The opposition to the flow of electrical current. Resistance is measured in Ohms.

RMS Power at 2 ohms This spec tells you how much more power your amp delivers when presented with a 2-ohm stereo load. You can achieve a 2-ohm load by using parallel wiring or by using 2-ohm speakers. Theoretically, amp output should exactly double as the impedance drops from the usual 4 ohms to 2 ohms.

However, amp makers use different degrees of regulation on power supplies, which can restrict the actual increase in output. *the lower the final impedance at the amp the lower the sound quality but the easier/cheaper it is to power*

2. Do locomotives on trains have a transmission?

If you are talking about a if you are talking about a diesel electric locomotive then no. They do not have a mechanical transmission. What they do have is a transition mode, which changes the output of the traction Motors from a high torque to a high speed mode.

In this case, relays simply change the method of output from series to parallel.I did however work on a mechanical driven streetcar which had a transmission. It also had a gasoline engine. But because trains need the ability to go forward as fast as they can go backward, it also required a third device in the output shaft that selected forward and reverse.

Of course the transmission also had a reverse option so if both devices were in Reverse you would go forward at a very low speed.Do locomotives on trains have a transmission?

3. Why can some americans be so arrogant about ww2?

Hello, Well we need not talk about how good each soldier is: 1) Hitler really did not want war with Great Britain which is part of the reason he dragged his feet backed off Sea Lion and turned on the Soviets. I've got a documentary from Lion Television showing he could have taken Britain in 6 weeks had he given it his all. This fighting in the cities, forests and hills never surrender talk would have eventually ended as Heydrich sorts of policies would have been brought in where people would be rounded up at random and shot for guerrilla actions of the home guard hence encouraging the people to rat out these partisans.

One should look to the behavior of a what if scenario by reading how the Brits behaved on the Channel Islands when the Germans occupied them. 2) You know Stalin had no love for Americans but he said that if it had not been for the industrial might and output of the USA, the war would have certainly been lost. That is the crux of the matter in my books.

3) One comment from a "few" Americans that does annoy me is that they tell the French that if it were not for us, you would all be speaking German. True but they owed France one because if it was not for French intervention in the American Revolution, Americans may well have been singing God Save the King for at least another few centuries. The money France put into this drained their resources and treasuries which in turn helped to facilitate the French Revolution.

Cheers, Michael Kelly.

  • Solar Street Light - Wikipedia of Solar Street Lights

    Raised light sources which are powered by solar panels

    Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated into the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night.

    Most solar lights turn on and turn off automatically by sensing outdoor light using solar panel voltage. Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not in the sky for an extended period of time. Older models included lamps that were not fluorescent or LED. Solar lights installed in windy regions are generally equipped with flat panels to better cope with the winds.

    Modern designs use wireless technology and fuzzy control theory for battery management. The street lights using this technology can operate as a network with each light having the capability of performing the turning on and off of the network.

    The solar panel is one of the most important parts of a solar street light, as the solar panel can convert solar energy into electricity that the lamps can use. There are two types of solar panels commonly used in solar street lights: mono-crystalline and polycrystalline. The conversion rate of mono-crystalline solar panels is much higher than their poly-crystalline counterparts. Solar panels also vary in wattage systems .

    LEDs are usually used as the primary lighting source of modern solar street lights, as the LED will provide much higher luminosity with lower energy consumption. The energy consumption of an LED fixture is at least 50% lower than the HPS fixture counterpart which is widely used as the lighting source in traditional street lights. A lack of warm-up time in LEDs also allows for use of motion detectors for additional efficiency gains.

    Batteries will store the electricity generated by the solar panel during the day and provide energy to the fixture during the night. The life cycle of the battery is very important to the lifetime of the light and the capacity of the battery will affect the backup days of the lights. There are two types of batteries commonly used in solar-powered street lights- gel cell deep cycle batteries as well as lead acid batteries. Lithium-ion batteries are also popular due to their compact size.

    Strong poles are necessary to all street lights, especially to solar street lights as there are often components mounted on the top of the pole: fixtures, panels and sometimes batteries. However, in some newer designs, the PV panels and all electronics are integrated in the pole itself. Wind resistance is also a factor.

    In addition, accessories do exist for these types of poles, such as a foundation cage and battery box.

    Each street light can have its own photo voltaic panel, independent of other street lights. Alternately, a number of panels can be installed as a central power source on a separate location and supply power to a number of street lights.

    All-in-one type solar street lights are gaining popularity due to their compact design which incorporates all of the parts necessary in a compact manner including the battery.

    The city of Las Vegas, Nevada was the first city in the world that tested new EnGoPlanet Solar Street lights which are coupled with kinetic tiles that produce electricity when people walk over them.

    • Solar street lights are independent of the utility grid. Hence, the operation costs are minimized.

    • Solar street lights require much less maintenance compared to conventional street lights.

    • Since external wires are eliminated, risk of accidents are minimized.

    • Separate parts of a solar panel system can easily be transported.

    • Risk of theft is higher as equipment costs are comparatively higher.

    • Snow or dust, combined with moisture can accumulate on horizontal PV-panels and reduce or even stop energy production.

    • Rechargeable batteries will need to be replaced several times over the lifetime of the fixtures adding to the total lifetime cost of the light.

    The charge and discharge cycles of the battery are also very important considering the overall cost of the project.

  • The Price of Solar Street Lamp Is Lower and Lower. What's the Reason?

    The Price Of Solar Street Lamp Is Lower And Lower. What is The Reason? The reduction of the price of the production line equipment results in the reduction of the production and manufacturing cost of each component of the solar street lamp.

    For example, in the past two years, the price of a solar powered lithium battery production machine and equipment can reach more than 100000 yuan, and now it has already dropped to more than 50000 yuan. The decrease in the price of raw materials is the key reason for the price of solar street lamps. The price of the core of the solar power panel has declined sharply, and the price of the silicon used in the solar photovoltaic panel has declined sharply, which will surely reduce the price of the solar street lamp.

    As for the common 6-meter solar road lamp pole, the standard wall thickness must be 2.75 in the previous period. Now, the wall thickness has already been guaranteed to be 2.3 or even 2.0. As a result, the necessary steel plate price will be reduced, and the price of the whole long pole will be reduced.

    Like solar street lamp battery panel, the product standard page of solar power panel is decreasing, which will cause a lot of reduction in the price of a complete set of solar street lamp. 4、 More and more solar street lamp manufacturers The total number of solar street lamp manufacturers has become more and more, so the market competition has become more and more intense, and the competitiveness has been improved, resulting in many manufacturers in order to obtain customers and reduce profits, so the price of solar street lamp has naturally declined sharply. The price of solar street lamp is getting lower and lower.

    For customers, good things are wrong. Good things are that customers can spend less and less money to buy suitable products. However, the wrong thing is that the quality level of solar street lamps in the sales market has become more uneven.

    Customers must have basic professional skills in solar street lamps before they can buy suitable ones. Therefore, customers must be careful when purchasing solar street lamps!

Power calculation of Outdoor Solar Street lights
Power calculation of Outdoor Solar Street lights
Outdoor solar street light designOutdoor solar street lights are composed of solar panels (including brackets), lamp holders, control boxes (with controllers and batteries, etc.), and light pole foundations. Solar street lights are generally separate power supply systems and are not connected to the power supply network of conventional street lights. There are three main types of solar street light systems: 12V, 3.2V, and 3.7V.Solar street light battery selection1. Type of outdoor solar street light battery Solar cells convert solar energy into electricity. There are two more practical ones, such as monocrystalline silicon and polycrystalline silicon. 1) The performance parameters of monocrystalline silicon solar batteries are relatively stable, suitable for use in places where the average sunshine time exceeds 4 hours; 2) Polysilicon solar panels are suitable for use in places where the sunshine time is less than 4 hours;2. Working voltage of the outdoor solar street light battery The working voltage of the solar street light battery is about 1.5 times of the battery voltage to ensure the normal charging of the lithium battery. For example, 5V~6V is needed to charge the 3.2 battery.Solar street light battery requires 15-18V solar battery to charge 12V lithium battery. To charge the 24V lithium battery, a 33~36V solar battery is required.   The following mainly introduces the relationship between the power of the light source, the voltage capacity of the lithium battery, and the volt power of the solar street light panel.W (energy) = P (power) × T (time)According to the law of conservation of energy, the solar panel converts light energy into electrical energy through photoelectric conversion and is stored in a lithium battery. The electrical energy in the lithium battery is converted into light energy to provide energy to the LED at night. The three have a common unit called watts. When Wh, 1Wh=1W × 1h, for example, the energy consumed by a 1W light for one hour is 1Wh. There is another word in physics that means energy, called Joule J, 1J = 1W × 1S (seconds), for example, A 1W heating wire generates 1J in 1 second, so 1Wh = 1J × 3600s = 3600J. Both actually represent energy. The difference is that Joule is generally used to represent heat energy, such as the very classic Joule's law in physics. (Joule's law is the law that quantitatively states that conduction current converts electrical energy into heat. The content is: the heat generated by the current passing through the conductor is proportional to the square of the current, proportional to the resistance of the conductor, and proportional to the time it takes to energize.Why LED lights generate heat is actually because part of the electrical energy is converted into heat energy. The greater the current, the greater the heat generation, and the greater the resistance, the greater the heat generation. Therefore, the high-power LED lights of the mains must be designed for heat dissipation. Solar energy Why do we say that the thickness of the copper wire is important? It is also closely related to this Joule's law. )W=U (Lithium battery voltage) × C (Lithium battery capacity)C (Lithium battery capacity) = I (current) × h (time)W=U (lithium battery voltage) × I (current) × h (time) = P (power) ÷ h (time)The maximum charging current of the solar panel is I (current) = P (solar panel power) ÷ U (solar panel voltage)We take the average sunshine time as the working time of the solar panel, and the capacity that the solar panel can charge the battery in a day is: C (capacity) = I (current) × h (average sunshine time) = P (solar panel power) ÷ U (Solar panel voltage) × h (average sunshine time)The energy-charged into the lithium battery is: W = U (lithium battery voltage) × C (capacity)Theoretically, the energy used by the lamp holder in a day cannot exceed the energy of the solar panel to charge the lithium battery in a day, otherwise the solar lamp will not be able to light up all night.
