unit of electricity resistance
ohm
tiny negatively charged particles
electrons
provides the force to move the electrons in the conducting material
source
more current flows than the line is designed to carry
overload
measure of how much electrical energy is being used per second
watt
electrons move at an even rate and flow in one direction
direct current
positive terminal and negative terminal and produces direct current only
battery
appliance has been certified to operate safely under the conditions the instructions specify
UL rating
technical name for any electrically powered appliance
load
electrons flow first in one direction then in another direction

power source most often used in a salon, produce alternating current
generator
how many watts does a light bulb use per second
25,60, or 100 watts per second
unit of electric strength
amp
changes direct current to alternating current
inverter
when the path is broken
open circuit

1000 per second
the movement of electricity along a path called a conductor
electric current
changes alternating current to direct current
rectifier
path of electron flow from the source to operate an appliance
closed circuit
how difficult is is to push electrons through a conductor
