Terms | Definitions |
|---|---|
Charge | The fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed. |
Conductor | Material, usually a metal, through which charge can flow |
Conservation of charge | The principle that net electric charge is niether created nor destroyed but is transferred from one material to another |
Coulomb | The SI unit of charge equivalent to the charge of 6.24 x 10^18 electrons or protons |
Coulomb's Law | The electrical force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges |
Electrical Force | A force that one charge exerts on another |
Electrically Polarized | An atom or molecule that is slightly more positive or nagative on one side than the other |
Electrostatics | The study of electric charges at rest |
Grounding | Allowing charges to move freely along a connection between a conductor and the ground |
Induced | Electric charge that has been redistributed on an object because of the presence of a charged object nearby |
Induction | The charging of an object without direct contact |
Insulator | A material that is a poor conductor of electricity |
Semiconductor | A material that can be made to behave as either a conductor or insulator of electricity |
Superconductor | A material that has no resistance to flow of charge |
