# Problem: If the current through an inductor were doubled, the energy stored in the inductor would be __________A. quartered.B. quadrupled.C. the same.D. halved.E. doubled.

###### FREE Expert Solution

The energy stored in the inductor:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{2}}{\mathbf{L}}{{\mathbf{i}}}^{{\mathbf{2}}}}$

From the equation, energy stored in the inductor is directly proportional to the square of the current through the inductor.

###### Problem Details

If the current through an inductor were doubled, the energy stored in the inductor would be __________

A. quartered.
