Capacitors

displacement current

Electrical equipment; Capacitors

A current which exists in addition to ordinary conduction current in ACcircuits. It is proportional to the rate of change of the electric field.

disruptive discharge

Electronic components; Capacitors

The sudden and large increase in current through an insulation medium due to the complete failure of the medium under the electrostatic stress.

The tangent of the loss angle of the insulating material. A measure of the power factor (or losses) of a capacitor, given as D.F. = 6.28 fRC X 100%, where R is the equivalent series resistance (ESR) ...

dv/dt

Electrical equipment; Capacitors

Change in Voltage divided by Change in Time, usually expressed in Volts per uSec.

electric double layer capacitor (EDLC)

Electrical equipment; Capacitors

Next-generation energy storage device that will be used as an auxiliary power supply and the combined use with photovoltaics equipment and hybrid electric cars. Also known as supercapacitors or ...

electrode

Electrical equipment; Capacitors

A conductor, not necessarily metal, through which a current enters or leaves a capacitor.

electrolytic capacitor

Electrical equipment; Capacitors

A polarized capacitor exhibiting a very high capacitance/volume ratio that consists of two electrodes immersed in an electrolyte, with a chemical film that acts as a dielectric on one or both ...
