Electricity
Def: a form of energy that results from the interaction of charged particles, such as protons and electrons.
-
Static Charge
Def: an electric charge that tends to stay on the surface of an object, rather than flowing away quickly.
-
Charging By Friction
a process in which objects made from different materials rub against each other, producing a net static charge on each object.
-
Electrostatic Series
Def: a list of materials that have been arranged according to their ability to hold on to electrons.
-
Insulator
A material in which electrons cannot move easily from one atom to another.
-
Conductor
A material through which electrons can flow easily between atoms.
-
Semiconductor
A material in which electrons can move fairly well between atoms.
-
Ground
An object that can supply a very large number of electrons to, or can remove a very large number of electrons from, a charged object, thus neutralizing that object.
-
Electroscope
A device for detecting the presence of an electric charge.
-
Charing By Contact
Generating a net charge on a neutral object by touching it with a charged object.
-
Laws Of Electric Charges
Laws that describe how two objects interact electrically when one or both are charged.
-
Electric Field
A property of the space around a charged object, where the effect of its charge can be felt by others.
-
Induced Charge Seperation
the movement of electrons in a substance, caused by the electric field of a nearby charged object that is not in direct contact with the substance.
-
Ion
A positively or negatively charged atom or group of atoms.
-
Lightning Rod
A metal sphere or point that is attached to the highest part of a building and connected to ground.
-
Electrostatic Precipitator
A type of cleaner that removes unwanted particles and liquid droplets from a flow of gas.
-
Van de Graaff Generator
A device that accumulates very large charges.
-
Radiation Dosimeter
A small device that detects and measures exposure to radiation.
