# An L-R circuit has a cell of e.m.f. E, which is switched on at time $$t = 0$$. The current in the circuit after a long time will be

A
Zero
B
ER
C
EL
D
EL2+R2

Solution

## The correct option is D $$\dfrac{E}{R}$$Clearly after long time inductor behaves as a straight neitherHere circuit chargesRefer image,Here $$I=\dfrac{E}{R}$$here correct answer is option $$B$$PhysicsNCERTStandard XII
