Neglecting losses in a transformer, it's input and output are equal.
a.) current
b.) voltage
c.) power
d.) turns of wire

Neglecting losses in a transformer, it's input and output power are equal. (C)

The input power in the transformer are equal to the output power of a transformer.

Answer : Option C

Explanation:

The transformers have power on either side as input or output to be constant. This is so because the transformers are the electrical device which transfer the energy between the circuits. There are two types of transformers, step up transformers and step down transformers.

Both follows the following expression of power = voltage x current. According to the type of transformer, the turns of wire and voltage and current are kept varying but the power remains constant.
