ELECTRICAL ENGINEERING (DEFINITIONS WITH CORRECT MEANINGS).7
1. Alternating current (ac) - correct answer the current flow where polarity is constantly
changing.
2. American wire gauge (awg) - correct answer a system for sizing round wires based on their
cross-sectional area where smaller numbers represent larger wire.
3. Ammeter - correct answer a meter that is used to measure current.
4. Atom - correct answer a microscopic building block of matter, made up of electrons,
protons, and neutrons.
5. Battery - correct answer an electrical connection of two or more cells.
6. Capacitor - correct answer a component that consists of two conductive plats separated by
an insulator called a dielectric. Capacitors can store and electrical charge on their plates.
7. Cell - correct answer a device that generates electricity through chemical action.
8. Circuit board - correct answer commonly known as a pcb (printed circuit board). A rigid
piece of insulation (typically fiberglass) is used as a platform for circuitry. Thin copper tracks
are laid on the fiberglass and electronic components are soldered to the track.
9. Compact florescent lamp (cfl) - correct answer a lamp that works on the same principle as
the fluorescent lamp but designed to fit into normal light sockets.
10. Conductor - correct answer a material with low resistance that easily passes electrons from
one atom to another.
, 11. Continuity tester - correct answer a tool used to test if there is a complete path between
two points.
12. Coulomb - correct answer the measure of the amount of electricity. One coulomb is equal
to 6,240,000,000,000,000,000 (6.24 × 1018) electrons.
13. Current - correct answer the measure of electrons per unit time.
14. Diode - correct answer a component that limits current flow to one direction. Can be used
as rectifiers to change ac to pulsating dc.
15. Direct current (dc) - correct answer current flow in one direction, where polarity never
changes.
16. Electrical engineering - correct answer the design and construction of electrical and
electronic components and devices.
17. Electricity - correct answer the movement of electrons
18. Electrode - correct answer a solid conductor through which electricity enters or leaves a
medium.
19. Electron - correct answer a negatively charged subatomic particle.
20. Fluorescent lamp - correct answer an energy-efficient lamp that uses a long tube coated on
the inside with phosphorous and filled with an inert gas. Mercury inside of the tube is
ionized, creating ultraviolet light, which causes the phosphorous to glow.
21. Gas discharge lamp - correct answer a lamp that creates light when gas inside of a globe is
ionized and glows.
