Can transformers generate power?

Power is equal to voltage times current. Transformers can never increase power. If their voltage is increased, current decreases and if they decrease voltage the current increases. Chargers that are used for cell phone and camera have electric transformers to reduce the voltage from your wall socket to a lower level.

Also, why there is difference between input power and output power of transformer?

The INPUT is what sort of electrical system you need to supply to the adapter (i.e. what your power company supplies). The OUTPUT is what is supplied to your device. Note that he amount of DC electrical power is calculated by multiplying the current by the voltage (P=I·V).

Likewise, how are transformers made? Most transformer coils are made from copper wire which has resistance in Ohms, ( Ω ). When a load is connected to the transformers secondary winding, large electrical currents flow in both the primary and the secondary windings, electrical energy and power ( or the I2 R ) losses occur as heat.

Besides, how does a power transformer work?

A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to "step up" or "step down" voltages and works on the magnetic induction principle. When voltage is introduced to one coil, called the primary, it magnetizes the iron core.

Can single phase transformers be used for three phase applications?

Yes. Any single phase transformer can be used on a three phase source by connecting the primary leads to any two wires of a three phase system, regardless of whether the source is three phase 3-wire or three phase 4-wire.
