When a battery is connected across a series combination of self inductance L and resistance R , the variation in the current i with time t is best represented by

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
`i=i_(0)(1-e^(-(R)/(L)t))`. At t = 0,i = 0.
At `tgtgttau=(L//R),i=i_(0).`
