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 42 02, and that in circuit 2 is 84 22. Determine (a) the ratio ₁/2 of the emfs and (b) the ratio 1₁/12 of thecurrents in the circuits. (c) If the speed of the rad in circuit 1 were twice that in circuit 2, what would be the ratio P₁/P2 of the powers inthe circuits?(a) ₁/2 = Number(b) 1₁/12 =Number(c) P₁/P₂ = NumberjelaiiXXXXXx L xXTUnitsUnitsXUnitsXXConducting railX X XXXX>>
