When current (I) in R-L series circuit becomes constant, where L is a pure inductor, which of the following given statements is/are correct?

A

voltage across R is RI.

B

Some part (not 100%) of the energy supplied by the battery will be dissipated in R and remaining will continue to store in L.

C

voltage across L is equal to zero.

D

magnetic energy stored is `1/2 LI^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
When the current becomes constant, the p.d across inductor will become zero. Hence the entire p.d. Will be across R.
Also energy stored in the inductor becomes constant if current through it becomes constant.
