Heavy Duty Mechanic – Foundations of Electricity (Basic Electrical Systems Study Guide)
what is current - correct answer ✔✔current is the movement of electrons in a conductor.
Measured in amps.
conductor - correct answer ✔✔metallic element, 1-3 electrons
insulator - correct answer ✔✔non-metallic element, 5-8 electrons
semi - conductor - correct answer ✔✔not conductor, nor an insulator. only has 4 electrons.
rectifier - correct answer ✔✔converts A/C to D/C
A/C - correct answer ✔✔alternating current
D/C - correct answer ✔✔direct current
voltage - correct answer ✔✔electromotive force, electrical pressure, charge pressure
resistance - correct answer ✔✔opposition to flow of electrons
amp - correct answer ✔✔measure of current
ohm - correct answer ✔✔measure of resistance
fuse - correct answer ✔✔protects circuit from excessive current flow
, anofe - correct answer ✔✔positive plate
cathode - correct answer ✔✔negative plate
electron drift - correct answer ✔✔electrons moving from one orbit to another
free electron - correct answer ✔✔electrons in the outer orbit that are easy to force from one
atom to another
what are the 6 methods to generate electron flow - correct answer ✔✔FRICTION - Static
electricity is generated when electrons are added or removed from an object
CHEMICAL - 2 different metals submerged in an electrolyte solution
LIGHT - Some materials give off electrons when bombarded by light.
HEAT - The junction of 2 dissimilar metals, when heated, will produce electron flow
MAGNETISM
INDUCTION - when a conductor is passed through a magnetic field an electric current is
generated
what does a basic circuit need - correct answer ✔✔switch, wire, source, ground, fuse, load
balanced atom - correct answer ✔✔equal amount of protons and electrons
conventional theory - correct answer ✔✔flow from positive to negative
electron theory - correct answer ✔✔flow from negative to positive
