Power supplies
Ionisation
Electrical equipment; Power supplies
Generally the dissociation of an atom or molecule into positive or negative ions or electrons. Restrictively, the state of an insulator whereby it facilitates the passage of current due to the ...
Charge
Electrical equipment; Power supplies
In electrostatics, the amount of electricity present upon any substance that has accumulated electric energy.
Insulation
Electrical equipment; Power supplies
Material having a high resistance to the flow of electric current to prevent leakage of current from a conductor.
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.
Plastic
Electrical equipment; Power supplies
High polymeric substances, including both natural and synthetic products, but excluding the rubbers, that are capable of flowing under heat and pressure at one time or another.
Solar array
Electrical equipment; Power supplies
Solar cells connected in series and/or parallel to generate power. Often the sole power source for a spacecraft.
