## Inductor SOLVED

 Good day Team, Question: A current of 4A flows in an inductor, and the energy stored by the inductor in joules is 12J, what will be the value of the inductor in henry? by S.Tech February 17, 2018

 Energy stored in the magnetic field of an inductor is $$E = \frac {1} {2} L I^2$$ So we can solve for $L$: $$L = \frac {2 E} {I^2}$$ or with your numbers: $$L = \frac {2 (12\ \text{J})} {(4\ \text{A})^2}= 1.5\ \text{H}$$ ACCEPTED +1 vote by mrobbins February 17, 2018
