In a step-up transformer, the turn ratio is 1 2 . A Leclanche cell (emf = 1.5 V) is connected across the primary. The voltage developed in the secondary would be
A) 3.0V
B) 0.75V
C) 1.5V
D) zero
Correct Answer:
D
Solution :
Transformer is an AC device. This does not work on DC. Hence, output voltage is zero.
