| conductor | material in which electrons can move or that transfers heat easily |
| electric current | the flow of electric charge, measured in amperes |
| electric discharge | rapid movement of excess charge from one place to another |
| circuit | closed conducting loop for electrical current to flow continually |
| electric field | surrounds every electric charge and exerts forces on other charges |
| electric force | attractive or repulsive force exerted by all charged objects on each other |
| electric power | rate at which electrical energy is converted into other forms of energy |
| force | a push or a pull |
| insulator | material in which electrons cannot move easily |
| ion | atom that is positively or negatively charged because it has gained or lost electrons |
| Ohm's law | states that the current in a circuit equals the voltage divided by the resistance in the circuit |
| parallel circuit | cricuit that has more than one path for electric current to follow |
| power | the rate at which energy is tranferred |
| resistance | a measure of how difficult it is for electrons to flow in a material |
| series circuit | circuit that has only one path for electric current to follow |
| static charge | imbalance of electric charge on an object |
| voltage | a measure of the amount of electrical potential energy an electron flowing in a circuit can gain |
