Calculates the stored Energy in an Inductor.
Enter 'x' in the field to be calculated.
The stored Energy in an Inductor in which flows an electric current is given by the following formula,
`E = 1/2 * L * i^2`
E : stored Energy in the inductor in joule
L : inductance of the Inductor in henry
i : electric current flowing through the Inductor in Ampere
