Capacitors

Aerogel capacitor

Electrical equipment; Capacitors

These capacitors use carbon aerogel to attain immense electrode surface area, can attain huge values, up to thousands of farads. EDLCs can be used as replacements for batteries in applications where ...

Aluminium electrolytic capacitor

Electrical equipment; Capacitors

Aluminium Electrolytic Capacitors are compact but “lossy”. They are available in the range of <1 µF to 1,000,000 µF with working voltages up to several hundred volts DC. The dielectric is a thin ...

Coupling

Electrical equipment; Capacitors

The use of a capacitor to connect two circuits. In using the capacitor, only the AC voltage (component) is passed.

Crest factor (lamp current crest factor)

Electrical equipment; Capacitors

Ratio of peak lamp current to RMS or average lamp operating current.

Critical voltage (of gas)

Electrical equipment; Capacitors

The voltage at which a gas ionises and corona occurs, preliminary to dielectric breakdown of the gas.

Dielectric

Electrical equipment; Capacitors

The insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have ...

Dielectric absorption

Electrical equipment; Capacitors

That property of an imperfect dielectric whereby there is an accumulation of electric charges within the body of the material when it is placed in an electric field.
