When a certain circuit consisting of a constant e.m.f. E an inductance L and a resistance R is closed, the current in, it increases with time according to curve 1. After one parameter (E, L or R) is changed, the increase in current follows curve 2 when the circuit is closed second time. Which parameter was changed and in what direction
                                

  • (A):L is increased
  • (B):L is decreased
  • (C):R is increased
  • (D):R is decreased

Best Answer

Correct Answer:

(A): L is increased
