Capacitors

insulation resistance

Electrical equipment; Capacitors

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, ionization

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 ...

lon, lonization

Electrical equipment; Capacitors

mica capacitor

Electrical equipment; Capacitors

This is made of metal foil plates that are separated by sheets of mica (the dielectric). The whole assembly is encased in molded plastic. Since the capacitor parts are molded into a plastic case, ...
