Current in a coil of self-inductance 2.0...

Current in a coil of self-inductance `2.0 H` is increasing as `I = 2 sin wt^(2)`. The amount of energy spent during the period when the current changes from `0` to `2 A` is

Text Solution

Verified by Experts

The correct Answer is:
4
Amount of energy invested is same as stored energy in the indictor. Amount of energy stored in an inductor can be written as follows:
`U= (1)/(2)Li^(2)= (1)/(2)xx 2 xx 2^(2)= 4 "joules"`
Hence, answer is 4.
