The space around a charged object in which another charged object experiences an electric force.

Energy is transmitted rapidly

The process by which and electric current is made by changing a magnetic field

Electric charge at rest. Generally produced by friction or induction.

A material in which charges can move easily

A material of such low conductivity that the flow of current through it is negligible.

The release of electricity stored in a source

The rate at which charges pass through a given point.

The opposition presented to the current by a material or device.

Electromotive force or potential difference expressed in volts

The difference between the potentials of two points in an electric field.

A closed path through which an electric current flows or may flow

Closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit

An abnormal, usually unintentional condition of relatively low resistance between two points of different potential in a circuit, usually resulting in a flow of excess current

A device for interrupting an electric circuit to prevent excessive current, as that caused by a short circuit, from damaging the apparatus in the circuit or from causing a fire.

To melt something, such as metal or glass, by heating.
