A current i0 is flowing through an L−R circuit of time constant i0. The source of the current is switched off at time t = 0. Let r be the value of (−di/dt) at time t = 0.Assuming this rate to be constant, the current will reduce to zero in a time interval of

A long solenoid having 200 turns per centimeter carries a current of 1.5 A. At the center of the solenoid is placed a coil of 100 turns of cross-sectional area 3.14 × 10^−4 m^2 having its axis parallel to the field produced by the solenoid. When the direction of current in the solenoid is reversed within 0.05 s, the induced emf in the coil is
