Problem

An AC generator has a coil of 150 square loops, each of side 3 cm. The loops are placed in a 1.4T magnetic field and rotate with a frequency of 50 Hz. The generator is connected as input voltage Vto the primary coil of a transformer with N= 80, and 40 turns in the secondary coil. The output voltage of the transformer is connected to a resistor of resistance R = 120 Ω. What is the peak (maximum) value of the current I0 flowing through the resistor?
