###### PLAY
circuit
a closed loop path of conduction through which an electric current flows
open circuit
an incomplete path that will not permit an electric current to flow
closed circuit
a complete path for electric current
current electricity
the flow of electrons through material
potential difference
the difference in potential energy between charges in two different locations, voltage
volts
the SI unit of electric potential
voltage
potential difference, the difference of potential between two points
resistance
any opposition that slows down or prevents movement of electrons through a conductor, opposition to the flow of electricity
ohms
unit for measuring electric resistance
Ohms Law
a scienctific law stating that the strength of a current is equal to the voltage divided by the resistance of the circuit Amps=volts / ohms
ampere
the rate of electron flow in a circuit, the unit of current
amps
unit used to measure the amount of current in a circuit
