Question | Answer |
---|---|
Electrostatics | The study of electric charges at rest. |
Electrical Force | A force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract. |
Charge | The fundamental electrical property to which one reaction event stimulates one or more additional reaction events to keep the process going |
Conservation of Charge | The principle that net electric charge is neither created nor destroyed but is transferable from one material to another. |
Coulomb's Law | The relationship among eletrical force, charges, and distance: The electrical force between two charges varies directly as the product of the charges and inversely as the square of 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 18th 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 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 | Term applied to a voltage, electric field, or magnetic field that is created due to a change in or motion through a magnetic field or electric field. |
Induction | The charging of an object wothout 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 molecule in which the charges are aligned so that one side is slightly more positive than negative than the opposite side. |
