Although the transformer can step-up (or step-down) voltage, it cannot step-up power. Thus, when a transformer steps-up a voltage, it steps-down the current and vice-versa, so that the output power is always at the same value as the input power. Then we can say that primary power equals secondary power, ( P P = P S ). Power in a Transformer

Transformers at power plants boost the voltage up to 100,000 volts and sometimes much higher before sending electricity on its way over transmission lines. This lowers the current in the lines, reducing the wasted energy and making sure that as much power as possible makes it to customers at the other end.
A transformer functions under the law of energy conservation, which states that energy can neither be created nor destroyed, only transformed. Therefore, a transformer does not make electricity, it merely changes the voltage to suit the needs of the user. Transformers accomplish this change in voltage through the process of electromagnetic ...
A transformer typically consists of two separate coils with different numbers of turns of conductor wound around the same closed laminated iron core (see Figure 1). The primary winding is the coil in a transformer that is energized by the source. The secondary winding is the coil that is connected to the load.
Since instantaneous winding voltage is proportional to the instantaneous magnetic flux''s rate of change in a transformer, a voltage waveform reaching the same peak value, but taking a longer amount of time to complete each half-cycle, demands that the flux maintain the same rate of change as before, but for longer periods of time.Thus, if the flux has …
