permittivity

Electrical equipment; Power supplies

The dielectric constant multiplied by the permittivity of empty space, where the permittivity of empty space, 0 ε , is a constant appearing in Coulomb’s Law.

resistivity (specific insulation resistance)

Electrical equipment; Power supplies

The electrical resistance between opposite faces of a 1-cm cube of an insulating material, commonly expressed in ohmcentimeters. Sometimes called volume resistivity.

cathode

Electrical equipment; Power supplies

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

electric field intensity

Electrical equipment; Power supplies

The force exerted on a stationary positive charge per unit charge at a point in an electric field. Designated by E. Also known as electric field strength, electric field vector.

plasma temperature

Electrical equipment; Power supplies

The kinetic temperature of a thermal plasma. Often this is expressed in energy units (eV), giving the average thermal energy of an ion or electron in the plasma. The ion ...

dielectric strength

Electrical equipment; Power supplies

The maximum electrical potential gradient (electric field) that an insulating material can withstand without rupture, usually expressed in volts per mm of thickness.
