 Conductor | Material that allows electricity to flow through it freely |
| A non-conductor/ insulator | Material that doesn't allow electricity to flow through it freely |
| Resistance | measure of how difficult it is for electricity to flow through a material |
| Low resistance | good conductors have low resistance |
| High Resistance | good non-conductors or insulators have high resistance |
| Metals- | -are good conductors of electricity |
| Copper- | -is the best inexpensive type of a metal conductor |
| Silver- | -is an expensive good conductor |
| Iron- | -is a poor conductor |
| Non-Metal insulators | glass, wood, plastic, and rubber |
| Electricity- | -flows freely through a good conductor |
| Electricity does not- | -flow freely through a non-conductor or insulator |
| Series circuit | when all the parts of a circuit are connected |
| In a series circuit when one bulb is out- | -the other bulbs will go out |
| Parallel circuit | electrical circuit with more than one path |
| In a parallel circuit if one bulb goes out- | -the other bulbs will stay lit |
| Home circuits | are set up as parallel circuits |
