Multiple Choice

An ideal transformer contains a primary coil of 200 turns and a secondary coil of 120 turns.The secondary coil drives a current I through an R = 1-k $\varOmega$ resistor.If an input V_rms = 75 V is applied across the primary coil,how much power is dissipated in the resistor,R?

A) 4 W
B) 0.5 W
C) 1 W
D) 2 W
