WebSo each electron gains kinetic energy equal to the amount of energy transferred electrically. The electron starts from rest (near enough) so the kinetic energy gained is given by ½mv 2 where m is its mass and v is its speed. So we can say that: ½mv 2 = eV. The mass of the electron is m = 9 × 10-31 kg. The electronic charge is e = 1.6 × 10-19 C WebU = 1 2 q 2 C. Substituting. q = C V. in the equation above, we get. U = 1 2 C V 2. The energy stored in a capacitor is given by the equation. U = 1 2 C V 2. Let us look at an example, to better understand how to calculate the energy stored in a capacitor.
