Question: In an inductor of inductance L = 100 mH, a current of $ I=10A $ is flowing. The energy stored in the inductor is [Orissa PMT 2004]
Options:
A) 5 J
B) 10 J
C) 100 J
D) 1000 J
Show Answer
Answer:
Correct Answer: A
Solution:
$ U=\frac{1}{2}Li^{2}=\frac{1}{2}\times 100\times {{10}^{-3}}\times {{(10)}^{2}}=5J $
