A circuit consisting of a constant EMF E, a self-inductance L and a resistance R in sereis is closed at time `t=0`. The relation between the current i in the circuit and the time t is as shown by the curve. A in the figure-5.321. when one or more of parameters E,R and L are changed, the curve B is obtained. Then it is possible that:
