Capacitors

Resistivity

Electrical equipment; Capacitors

The ability of a material to resist passage of electrical current either through its bulk or on a surface. The unit of volume resistivity is the ohm-cm, of surface resistivity, the ohm.

Insulation

Electrical equipment; Capacitors

Material having a high resistance to the flow of electric current, which prevents leakage of current from a conductor.

The ratio of the applied Voltage to the total current between two electrodes in contact with a specific insulator. A measure of the resistance to a DC current flow through the capacitor under steady ...

Insulator

Electrical equipment; Capacitors

A material of such low electrical conductivity that the flow of current through it can usually be neglected.

Internal fuse

Electrical equipment; Capacitors

A device that disconnects capacitor operation from power distribution system in the event of excessive current.

Ion, ionisation

Electrical equipment; Capacitors

An electrified portion of matter of sub-atomic, atomic, or molecular dimensions such as is formed when a molecule of gas loses an electron (when the gas is stressed electrically beyond the critical ...

Joule (watt second)

Electrical equipment; Capacitors

Joule = 0.5 X Capacitance (Farads) X Voltage^2. The Joule is a measure of the amount of energy delivered by one WATT of power in one second or 1 million watts of power in one microsecond. The Joule ...
