A circuit cosisting of a constant e.m.f. 'E' a self induction 'L' and a resistance 'R' is closed at t=0 The relation between the current I in the circuit and time t is as shown by curve 'a' in the fig. When one or more of paraments E,R & L are changed, the curve 'b' is obtained The steady state current is same in both the cases Thenit is possible that: |

Answer» E & R are KEPT CONSTANT & L is increased |
