The current in a coil of self inductance...

The current in a coil of self inductance 2.0 henry is increasing according to `i= 2 sin t^(2)` ampere. Find the amount of energy spent during the period when the current changes from 0 to 2 amp.

Text Solution

Verified by Experts

The correct Answer is:
`4` joule
`DU=U_(f)-U_(i)`
`=1/2(l_(1)^(2)-l_(1)^(2))=4 J`
