By rearranging this equation to EE = Vq , we can see that another measure of energy can be made by multiplication of a change in electrical potential by the charge. For many applications in physics the Joule is far too large as a unit so instead the electron-Volt (ev) is used. To convert one ev to J
1.6 x 10**-19 C x 1 V = 1.6 x 10**-19 J
