Power supplies
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 temperatures need not be the ...
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.
frequency
Electrical equipment; Power supplies
The number of complete cycles or vibrations per unit of time.
