Energy Stored on a Capacitor

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. The voltage V is proportional to the amount of charge which is ...

Capacitor

A capacitor is made of two conductors separated by a non-conductive area. This area can be a vacuum or a dielectric (insulator). A capacitor has no net electric charge. Each conductor holds equal and opposite charges. The inner area of the capacitor is where the electric field is created. Hydraulic analogy.
