Question

Tum ratio in a step up transformer is 1 : 2 if a Lechlanche cell of 1.5 V is connected across the input, then the voltage across the output will be

• A. 0.1 V
• B. 1.5 V
• C. 0.75 V
• D. Zero

Answer 1

The correct option is D Zero

A transformer can not step up a d.c. input so output potential here will be zero. No potential will be induced in the secondary coil.
