Alternate derivation for energy stored by a capacitor

Remember that charging a capacitor means shifting charge from one of its plates (initially neutral) to the other (initially neutral). Thus one plate becomes more and more positively charged while the other becomes equally and oppositely charged. The shifting is most easily done by connecting a battery across the plates.

3 · Ans. 1-farad capacitor at a voltage of 1 volt stores 1-coulomb charge. Moreover, 1 coulomb is equivalent to 6.25e18 (6.25 x 10 18) electrons, and a current of 1 amp shows an electron flow rate of one coulomb each second.Hence a capacitor of 1 farad at 1 volt can store one ampere-second electron.
