Terms | Definitions |
|---|---|
 circuit | a closed loop path of conduction through which an electric current flows |

| 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 |
