If a dry cell of emf=1.5 V is connected across the primary of a step-up transformer of turn ratio 3:5, then calculate the voltage developed across the secondary.

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:
