The current in LR circuit if reduced to half. What will be the energy stored in it?
Options
- A4 times
- B2 times
- Chalf times
- D( 1 4 )^ th times
Correct answer
D. ( 1 4 )^ th times
Step-by-step solution
Energy stored in LR circuit is aligned E & = 1 2 LI ^2 ...(i) I ^ & = I 2 E ^ & = 1 2 ~L ( I 2 )^2 & = 1 4 1 2 LI ^2 E ^ & = 1 4 E aligned ...(given) ...[From(i)]
