Question
Turn ratio 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 out put will be
Options
A.0.1V
B.1.5V
C.0.75V
D.zero
Solution
A transformer can not step up a d. c.input so out potential here will be zero. Nopotential will be induced in the secondary coil.
