Hasan.

The L and I are in the numerator not beside 2.

Hasan said:   3 years ago
It's inversely proportional, Energy= 1/2 l i^2 then how does energy decreases when current decreases?

You are correct @Sumeet.

Sumeet you right. Thanks for explian it.

Yes, you are right @Sumeet.

Energy = 1/2 (L * I^2). If current will decrease energy will also decrease.

Inductor stores energy when current increases and gives stored energy when current through it decreases.

Sumeet said:   1 decade ago
As energy stored in a inductor=1/2*L*I^2 so if current decreases energy stored also decreases.

Because h=ni.
