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:

Options

A. E and R are kept constant and L is increased
B. E and R are kept constant and L is decreased
C. E and R are both halved and L is kept constant
D. E and L are kept constant and R is decreased.

Answer

A, C
