Chapter 10 Electricity

A form of energy that results from the interaction of charged particles

An electric charge that tends to stay on the surface of an object, rather than flowing away quickly

A process in which objects made from different materials rub against each other, producing a net static charge on each object

A list that ranks the objects ability to take negative charges.

A material in which electrons can't move easily from one atom to the other

e.g. plastic, wood, rubber

A material in which electrons can move easily between atoms

e.g. copper, aluminum, water

A material in which electrons can move fairly well between atoms

e.g. 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 neutralizing that object

• an instrument for detecting and measuring electricity

opposites attract, like charges repel, neutral attracts

a region around a charged particle or object within which a force would be exerted on other charged particles or objects.

the movement of electrons in a substance, caused by the electric field of a nearby charged object without direct contact between the substance and the object.

an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

a metal rod or wire fixed to an exposed part of a building or other tall structure to divert lightning harmlessly into the ground.

a device that removes suspended dust particles from a gas or exhaust by applying a high-voltage electrostatic charge and collecting the particles on charged plates.

a machine devised to produce a high voltage by means of an endless belt collecting electrostatic charge from a source and transferring it to a large isolated metal dome, on which a large charge accumulates.

Dosimeters measure an individual's or an object's exposure to radiated energy
