A transformer has 100 turns on primary coil and 300 turn on secondary coil. If 20V Ac is applied to the primary coil, what would be the secondary voltage?

the secondary voltage is 60 V.

Explanation:

Given;

number of turns on the primary coil, Np = 100 turns

number of turns on the secondary coil, Ns = 300 turns

voltage supply in the primary coil, Vp = 20 V

let the secondary voltage = Vs

Apply the following transformer equation to determine the secondary voltage;

Therefore, the secondary voltage is 60 V.
