| switch | something that opens and closes a circuit |
| series circuit | connected from + to -, only one path |
| parallel circuit | connected with more than one path |
| resistance | a way of measuring force against electricity or how easily electricity flows |
| resistance is found in a simple circuit in a _____ | light bulb |
| series circuit light bulbs appear _______ | dimmer |
| A bulb in a series circuit is dimmer because | the battery is shared and there is more resistance |
| parallel circuits has the bulbs that are_____ | separated,more than one path |
| Batteries in a parallel circuit are | independent of each other |
| Parallel circuit bulbs are | brighter |
| Benefit of connecting batteries in a parallel circuit | batteries last longer |
| power | voltage |
| adding more coils or more batteries | changes the strength of an electromagnet |
| You can use a magnet to create electricity by | moving it through coils of wire or coils of wire between magnets |
| safety ways | Don't touch electric when wet or wear insulated gloves |
| insulated wires | help protect people from shocks |
| conductors | silver, gold, aluminum, copper |
| insulators | glass, wood, rubber, plastic |
| A simple circuit | uses resistance to change the brightness of a bulb |
| uses resistance to change the brightness of a bulb | a dimmer switch |
