Question

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 each
circuit, but the bulb in circuit 1 has one-half the resistance of the bulb in circuit 2. The circuits are otherwise identical. The resistance of
the light bulb in circuit 1 is 40 02, and that in circuit 2 is 80 Q. Determine (a) the ratio 3₁/32 of the emfs and (b) the ratio 1₁/12 of the
currents in the circuits. (c) If the speed of the rod in circuit 1 were twice that in circuit 2, what would be the ratio P₁/P2 of the powers in
the circuits?
(a) 1/2= Number i
(b) 1₁1/12 =
Number i
(c) P₁/P₂= Number i
