1.	In the circuit shown in the figure, the jockey J is being pulled towards right, so that the resistance in the circuit is increasing. It’s a value at some instant is `5Omega`. The current in the circuit at this instant will be A. `4A`B. less than 4 AC. more thanD. may be less than or more than 4 A depending on the value of L
Answer» Correct Answer - C Since, yor are decreasing current in the circuit by increasing resistance of the circuit. Induced emf across inductor will support 20 V battery. Hence, net emf of the circuit is greater than 20 V or current in the circuit is more than 4 A.
