Term
Charge
Definition
The fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed.
Term
Conductor
Definition
Material, usually metal in which electricity flows through.
Term
Conservation of Charge
Definition
The principle that net electric charge is neither created or destroyed but transferable from one material to another.
Term
Coulomb
Definition
SI unit of charge.
Term
Coulomb's Law
Definition
The Electrical force between two charges varies directly as the product of the charges and inversely as the square of the distance between them.
Term
Electrical Force
Definition
A force that one charge exerts on another. Like charges repel, opposite charges attract.
Term
Electrically Polarized
Definition
Term applied to an atom or molecule in which the charges are aligned so one end is is slightly more positive or negative than the opposite, they attract.
Term
Electrostatics
Definition
The study of electric charge at rest.
Term
Grounding
Definition
Allowing a charge to move freely along a connection between a conductor and the ground.
Term
Induced
Definition
Term applied to an electric charge that has been redistributed on an object because of the presence of a charged object nearby.
Term
Induction
Definition
The charging of an object without direct contact.
Term
Insulator
Definition
A material that is a poor conductor of heat and that delays the transfer of heat.
Term
Semiconductor
Definition
Material that can behave as either an insulator or conductor of electricity.
Term
Superconductor
Definition
Material that has infinite conductivity at very low temperatures, so that the charge flows through it without resistance.
