batteries and generators
Waveform has constant amplitude over the pules duration (also known as a pulse wave)
Rectangular
a reusable safety device that breaks the flow of current when an overload occurs
circuit breaker
the movement of electricity along a path called a conductor
electric current
a unit of electric strength
amp
electrons move at an even rate and flow in only one direction
Direct current
a periodic waveform that instantly transitions between 2 levels of rise and fall times at a steady frequency
square
a safety device that contains a fine metal wire that allows current to flow through it
fuse
material that allows electricity to flow through it easily
conductor
a unit of electric pressure
volt
electrons flow first in one direction and then in the other
alternating current
is a periodic linear waveform that has equal rise and fall times
triangular

GFCI
a measure of how much electrical energy is being used per second
Watt
rate of cycling or frequency
