Electricity
A form of energy that results from the interaction of particles, such as electrons or protons
-
Static charge
- Static electricity
- an electrical 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 rubbing against each other, producing a net static charge on each object
-

-
Insulator
A material in which electrons can not move easily from one atom to another
-
Conductor
A material in which electrons can move 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 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 electrical charge
-
Charging by contact
Generating a net charge on a neutral object by touching it with a charged object
-
Laws of electric charge
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 electrical field of a nearby charged object that is not in direct 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 if a building and connected to the 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
