Answer:

option c

Explanation:

A step-down transformer is an electrical device that reduces the voltage of an alternating current (AC) power supply. It consists of a primary winding, a secondary winding, and an iron core. When an AC voltage is applied to the primary winding, it creates a fluctuating magnetic field in the iron core.

Step down transformer is used to step down the voltage. Since there is no power loss during transmission, the power is same in primary and secondary coils. Thus the coil having a lower voltage will have a higher current. Hence, current in the secondary coil is more.

but there are more coil on primary side and fewer on the secondary side
