GLOSSARY
AC Voltage A voltage that varies, usually above and below zero volts, thus causing the current to alternate.
Atom The smallest part into which matter can be divided and still maintain its identity.
Avalanche An increase in moving particles due to sudden impact.
Electric Field The force that exists when a difference in charge occurs.
Electron A tiny negatively charged particle that rotates around the nucleus of an atom.
Electron-volts A unit of energy equal to 1.602 x 10
-19
joules.
Energy Effective force. The capacity for doing work.
Force The cause that changes bodies from a state of rest to motion or from motion to rest.
Gas An air-like substance without definite shape or volume, tending to expand indefinitely when
unconfined. One of the three forms in which matter can exist.
Ion An electrically charged particle that enables the flow of electricity.
Liquid One of the three forms in which matter can exist separately and still maintain the character of
that substance.
Neon A gaseous element, inert, colorless, and found in the atomosphere.
Photons A unit of light measurement.
Power The mechanical rate at which energy is exerted or work done.
Proton The smallest unit of positive charge in an atom.
Solid One of three forms in which matter can exist, having a definite volume and a definite shape.
Transformer A device used for converting an alternating electric current from one voltage to another.
Xenon A gaseous element which belongs to the group of inert gases. It occurs in air in minute traces.
