Question | Answer |
---|---|
Electrostatics | The study of electric charges at rest. |
Electrical Forces | A force that one charge exerts on an other. When the charges are the same sign, they repel; when the charges are the opposite, they attract. |
Charge | The fundamental electrical property to which the mutual attractions or repulsions between electrons or protons is attributed. |
Conservation of Charge | The principle that net electric charge is niether created nor destroyed but is transferable from one material to another. |
Coulomb's Law | The relationship among electrical force, charges, and distance: The electrical force between two charges varies directly as the product of the charges and inversely as the square of the distance between them. |
Coulomb | SI unit of charge. One coulomb (symbol C) is equal to the total charge of 6.24 x 10 to the power of 18 electrons. |
Conductor | (a) Material through which heat can be transferred. (b) Material, usually a metal, through which electric charge can flow. Good conductors of heat are generally good charge conductors. |
Insulator | (a) A material that is a poor conductor of heat and that delays the transfer of heat. (b) A material that is a poor conductor of electricity. |
Semiconductor | Material that can be made to behave as either a conductor or an insulator of electricity. |
Induced | (a)Term applied to electric charge that's been redistributed on object bc presence of charged object nearby. (b)Term applied to voltage, electric field, or magnetic field that's created due to change in or motion through magnetic field or electric field. |
Induction | The charging of an object without direct contact. |
Grounding | Allowing charges to move freely along a connection between a conductor and the ground. |
Electrically Polarized | Term applied to an atom or molocule in which the charges are aligned so that one side is slightly more positive or negative than the opposite side. |
