Electricity
A form of energy that results from the interaction of charged particles, such as electrons or protons
-
Static Charge(static electricity)
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
A list of materials that have been arranged according to their ability to hold o to electrons
-
Insulator
A material in which electrons cannot move easily from one atom to another (rubber)
-
Conductor
A material in which electrons can move easily between atoms (copper)
-
Semiconductor
A material in which electrons can move fairly well between atoms (silicon)
-
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
-
Charging 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 other objects
-
Induced Charge Separation
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 postively 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 the ground
-
Electrostatic Precipitator
A type of cleaner that removes unwated 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
