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
loader
B
ER
loader
C
EL
loader
D
EL2+R2
loader

Solution

The correct option is D $$\dfrac{E}{R}$$
Clearly after long time inductor behaves as a straight neither
Here circuit charges
Refer image,
Here $$I=\dfrac{E}{R}$$
here correct answer is option $$B$$
