Capacitors

Bypass (de-coupling)

Electrical equipment; Capacitors

The use of a capacitor to prevent the AC portion of a signal from a circuit element via a low impedance path in parallel with the circuit element.

Capacitance (capacity)

Electrical equipment; Capacitors

That property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a ...

Capacitive reactance (xc)

Electrical equipment; Capacitors

The opposition to the flow of alternating or pulsating current by a capacitor measured in ohms. The non-heating impedance component of the capacitor when AC flows: Xc = 1/(6.28fC)

Capacitor

Electrical equipment; Capacitors

An electrical/electronic part that stores electrical charges. In its simplest form it consists of two conducting surfaces separated by a dielectric.

Cathode

Electrical equipment; Capacitors

The electrode through which an electric current leaves a liquid, gas, or other discrete part of an electric current; the negatively charged pole of an electrochemical cell.
