WebAlthough 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 WebAC can be stepped up and down by using a transformer.
