Q166 / 180 · KCET 2011 · Physics
The energy stored in an inductor of self inductance $L$ henry carrying a current of $I$ ampere is
- A$\frac{1}{2} L^{2} I$
- Correct answerB$\frac{1}{2} L I^{2}$
- C$L I^{2}$
- D$L^{2} I$
Solution
The energy stored in an inductor $U=\frac{1}{2} L I^{2}$
Hence, the correct answer is option: 'B'.
