| electrical charge | a concentration of electricity |
| unlike charges | attract each other |
| like charges | repel each other |
| everything | contains electric charges |
| insulator | material in which charges do not move freely |
| conductor | material in which charges can move freely |
| circuit | a complete, closed path |
| current | how much electricity flows past in a given time |
| amps (amperes) | unit of measurement for current |
| electric potential energy | total stored energy the charges |
| potential difference | the change in total energy divided by total charge |
| battery | gives the charges a potential difference |
| resistance | property that indicates how much electricity changes to thermal/light energy |
| parts of a simple circuit | source of potential difference, conducting path,resistance |
| Ohm's Law | V/R = I |
