| A | B |
|---|
| ion | positivel;y or negatively charged atom |
| static charge | build up of electrical charge of an object |
| electric force | attractive or repulsiveforce exerted by all charged objects on each other |
| electric field | field through which electric charges exerts a force on each other |
| insulator | prevents transfer of electrical energy |
| conductor | easily transfers electrical energy |
| electric disharge | rapid movement of charge from one place to another |
| electric current | flow of electric charge; in solids - electrons; in liquids - ions |
| resistance | measure of how difficult it is for electrons to flow through a material |
| insulator has | high resistance |
| conductor has | low resistance |
| circuit | a closed conducting loop through which electric currents continuously flow |
| voltage | measure of how much electric energy a battery can provide, or amount of energy each electron can gain |
| ohm's law | current = voltage / resistance |
| series circuit | a circuit that has only one path for the electric current to follow |
| parallel circuit | circuit that has more than one path to follow |
| electric power | rate at which an appliance converts electrical energy to another form of energy |
| fuses | safety device that will limit the amount of current in wiring |
| power | = current x voltage |
| watt | unit of power |
| kilowatt | 100 uni8ts of power, unit in which electric companies charge customers by monthly |
| like charges | repel |
| unlike charges | attract |
| grounding | provides a pathway to the ground to drain excess charge into the earth |
| two basic types of circuits | series and paralell |
