The potential difference between two points in an electric field is the done in bringing a unit positive charge from one point to the other. It is measured in . The volt is defined as the potential difference between two points if one of work is done in bringing a charge of one from one point to the other.
An electric current is a flow of . The electric potential at a point is the potential difference between the and that point. The Earth's potential is taken to be .
The capacitance of a conductor is the ratio of the charge on the to its . It is measured in .
A parallel plate capacitor consists of two plates separated by a . Its capacitance is equal to the charge on the plate by the potential difference between the plates. The capacitance of a parallel plate capacitor is proportional to the of overlap between the plates and the of the dielectric, and is inversely proportional to the between its plates.
The energy stored in a capacitor is equal to the work done in the capacitor. Capacitors allow current to flow and block current.
