Back to Electromagnetic InductionA 10 cm long perfectly conducting wire PQ is moving with a velocity I cm/s on a pair of horizontal rails of zero resistance. One side of the rails is connected to an inductor L = 1 mH and a resistance R = 1\Omega as shown in figure. The horizontal rails, L and R lie in the same plane with a uniform magnetic field B = 1 T perpendicular to the plane. If the key S is closed at certain instant, the current in the circuit after 1 millisecond is x \times 10

A, where the value of x is ...........
[Assume the velocity of wire PQ remains constant (1 cm/s) after key S is closed. Given e
-1
= 0.37, where e is base of the natural logarithm]
