Term
|
Definition
| A building up at the negative terminal of a cell/battery which then flows from this terminal as negative charges repel one another. |

Term
| Electrical Potential Difference |
|
Definition
| *The change in potential energy per coulomb of charge. •Also called voltage •Measured in volts (V) •Measured using a voltmeter |
|
|
Term
| Electric Potential Energy |
|
Definition
| •Stored electrical energy •Ex. A battery has stored electrical energy because the electrons have the ability to do work after they leave the battery. |
|
