Capacitors

Critical voltage

Electronic components; Capacitors

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

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

Electronic components; 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.

Dielectric constant

Electronic components; Capacitors

That property of a dielectric which determines the electrostatic energy stored per unit volume for unit potential gradient.

Dielectric loss

Electronic components; Capacitors

The time rate at which electric energy is transformed into heat in a dielectric when it is subjected to a changing electric field.

Dielectric loss angle

Electronic components; Capacitors

The difference between 90º and the dielectric phase angle.

Dielectric phase angle

Electronic components; Capacitors

The angular difference in phase between the sinusoidal alternating potential difference applied to a dielectric and the component of the resulting alternating current having the same period as the ...
