The energy stored in an inductor 2H and current 4A is(a) 4(b) 8(c) 12(d) 16This question was addressed to me by my school teacher while I was bunking the class.I need to ask this question from Stokes Theorem in section Vector Calculus of Electromagnetic Theory

Answer»

The CORRECT CHOICE is (d) 16

To explain: From STOKE’s theorem, we can calculate energy stored in an INDUCTOR as 0.5Li^2. E = 0.5 X 2 X 4^2 = 16 units.
