Two circuits contain an emf produced by a moving metal rod. Thespeed of the rod is the same in each circuit but the bulb incircuit 1 has one-half the resisitance of the bulb in curcuit 2.The circuits are otherwiase indentical. The resisitance of thelightbulb in curcuit 1 is 55Ω and that in circuit 2 is 110Ω. Determine,(a) the ratio ε1/ε2 of the emfs and (b) theratio I1/I2 of the current in thecircuits. (c) if the speed of the rod in circuit 1 were twice thatin circuit 2 , what would be the ratio P1/P2of the power in the circuits.
