Simple Circuits

4. Short for the units used to measure how much electricity is flowing.
6. The tiny, negatively charged subatomic particles that zip through wires.
7. The "heart" of the circuit, such as a battery or a wall outlet, that provides energy.
10. A material (like rubber or plastic) that stubbornly blocks the flow of electricity.
11. The unit used to quantify resistance; named after a German physicist.
12. The steady flow of charge through a conductor; think of it like a river's tide.

1. A material (like copper or gold) that allows electricity to flow easily.
2. A circuit with multiple branches; a favorite for home wiring so one burnt-out bulb doesn't kill all the lights.
3. A circuit where components are lined up in a single path; if one breaks, they all stop.
5. The measure of how much a material holds back the flow of electricity.
8. The device used to intentionally "break" or "complete" the circuit path.
9. The electrical "pressure" or push from a power source.
