Question

A step-up transformer has 120 turns on its primary coil. It has 1150 turns on its secondary coil. The primary circuit is supplied with an alternating current at 120 V.
The current in the secondary circuit is 2.4 A. What current is in the primary circuit?

formula??
induced emf in secondary= (number of turns in secondary/ number of turns in promary)* applied emf in primary.

this can be changes to solve for applied emf in primary instead.
