Currents
flow of electrons in a conductor
Current Electricity
unit for measuring the rate of electrical flow
Ampere
path of electrical flow
Circuit
heat sensitive switch that automatically trips when electricity demand is too great; reusable
Circuit Breaker
This color usually signifies a "hot" wire
Black
cyclical reversing of direction of electron flow
Alternating Current (AC)
electrical pressure
Voltage
having multiple paths for current flow
Parallel Circuit
material that transmits electricity by allowing electrons to flow
Conductor
The direction a wire should be looped around a screw
Clockwise
flow of electrons in one direction
Direct Current (DC)
opposition to movement of electrons
Resistance
provides single path for current flow
Series Circuit
material that is a poor conductor of electricity
Insulator
Amount of insulation that should be stripped back on a wire
1/2"
the connection of a circuit to the earth for safety
Ground(ing)
a measurement of resistance
Ohm
circuit in which there is at least one place where current cannot flow
Open Circuit
heat sensitive devices that protect electrical circuits from overloads; cannot be re-used
Fuse
This type of wire is always wired to the green screw
ground
a device used to store electricity
Capacitor
measure of energy used by an electrical device
Watt
circuit where electricity flows back to the source and not through the appliance
Short Circuit
gang box with a blank cover that contains wire splices
Junction Box
