1.	The circuit shown consists of a switch (S), a battery (B) of emf E, a resistance R, and an inductor L. The current in the circuit at the instant the switch is closed is- (A) E/R (B) E/R(1 – e) (C) ∞ (D) 0
Answer» Correct Option :- (D) 0 Explanation :- Using the equation I = I₀ (1 − e^−t/t_L ) Put t = 0 we get I = 0 Just when the battery is closed inductor provides infinite resistance to the current flow ∴ current is zero initially.

Answer»

Correct Option :- (D) 0

Explanation :-

Using the equation I = I₀ (1 − e^−t/t_L )

Put t = 0 we get I = 0

Just when the battery is closed inductor provides infinite resistance to the current flow

∴ current is zero initially.
