Question

An AC electrical generator is made by turning a flat coil in a uniform constant magnetic field of 0.225 T. The coil consists of 29 square windings and each winding is 15.0 cm on each side. It rotates at a steady rate of 745 rpm about an axis perpendicular to the magnetic field passing through the middle of the coil and parallel to two of its opposite sides. A 7.80 Ωlight bulb is connected across the generator.

(a) Find the voltage and current amplitudes for the light bulb.

V0	=	_______V
i0	=	________ A

(b) At what average rate is heat generated in the light bulb?
______________ W

(c) How much energy is consumed by the light bulb every hour?
_____________ J
