At any instant a current of 2 A is increasing at a rate of `1 A//s` through a coil of indcutance 2 H. Find the energy (in SI units) being stored in the inductor per unit time at that instant.

Text Solution

Verified by Experts

The correct Answer is:
4
`U=1/2 Li^(2)`
Energy stroed per unit time
`(dU)/(dt) = 1/2 L2i (di)/(dt) =Li(di)/(dt) = 2 xx 2 xx 1 =4 J//s`.
