An inductor of inductance 10H carries a current of 0.2A. Calculate the energy stored in the inductor
A
0.1J
B
0.2J
C
1.0J
D
2.0J
Verified Correct Answer: B.
Physical Principles & Numerical Solution
The energy(W)stored in an inductor is calculated by the formula: \(\frac{1}{2}\)LI\(^2\)
= \(\frac{1}{2}\) x 10 x (0.2)\(^2\)
= 0.2J
