Two circuits contain an emf produced by a moving metal rod, like that shown in the drawing. The speed of the rod is the same in eachcircuit, but the bulb in circuit 1 has one-half the resistance of the bulb in circuit 2. The circuits are otherwise identical. The resistance ofthe light bulb in circuit 1 is 44 Q, and that in circuit 2 is 88 Q. Determine (a) the ratio 31/32 of the emfs and (b) the ratio 11/12 of thecurrents in the circuits.
