In a step up transformer, the turn ratio is 3 : 2. A battery of EMF 4.5V is connected across the primary windings of transformer. The voltage developed in the secondary would be:

Trune ratio in a step up trnsfromer is 1:2, if a Lechlanche cell of 1.5 V is conneted across the input, what is the voltage across the output?

In a step up transformer, the turn ratio is 1:10. A resistance of 200 Omega connected across the secondary draws a current of 0.5 A. What is the primary voltage?
