Inductors - Technical MCQs

Q1:

With 100 Vac applied to the primary of a transformer so that it draws 500 mA, what will be the 300 Vac secondary current?

A 1500 mA

B 200 mA

C 167 mA

D 150 mA

ANS:C - 167 mA

We have the formula v1/v2 = I2/I1.

By substituting values,

100/300 = I2/500.

We get 166.6 is similarly 167.
