How capacitor stored energy on charging obtain an expression?

1.	How capacitor stored energy on charging obtain an expression?
Answer» ANSWER: The energy stored on a CAPACITOR can be EXPRESSED in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the POSITIVE plate is equal to V dq, where V is the voltage on the capacitor.
