Unit 4 electricity glossary terms.txt

Electricity is the form of energy that results from the interaction of charged particles, such as electrons and protons.

An electric charge thta tends to stay on the surface of an object, rather than flowing away quickley.

Charging by friction is the process in which objects made from different materials rub against each other, producing a net static charge on a object.

A list of materials that have been aranged according to their ability to hold on to electrons.

A material in which electrons cannot move easily from one atom to another. Ex:Wood

A conductor is a material in which materials can move easily between atoms. Ex: Metal

A material in which electrons can move fairley well between atoms.Ex: Silicon

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 nutralizing that object.

A device for detecting the presence of an electric charge.

Generating a net charge on a neurtral object by touching it with a charged object.

Laws that describe how two objects interact electically when one or both are charged.

A property of space around a charged object, where the effect of its charge can be felt by other objects.

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.

A positively charged or negatively charged atom or group of atoms.

A metal sphere or point that is attached to the highest part of a building and connected to the ground.

A type of cleaner that can remove unwanted waste particles and liquid droplets from a flow of gas.

A device that accumualates very large charges.

A small device that detects and measures exposer to radiation.
