The current generator I_g‘ shown in figure, sends a constant current i through the circuit. The wire cd is fixed and ab is made to slide on the smooth, thick rails with a constant velocity v towards right. Each of these wires has resistance r. Find the current through the wire cd.
Figure
Ans : Current passing through the circuit initially = i
Initial emf = ir
Emf induced due to motion of ab, e = Blv
Net emf, e_net= ir - Blv
Net resistance = 2r
Thus, the current passing through the circuit is `` \frac{ir-Blv}{2r}``.
