Electrical Safety

2. A complete path where current flows.
5. A material that allows electricity to flow easily (like copper or aluminum).
9. The rate at which electricity is used or produced, measured in watts (W).
10. An unintended path with very low resistance that can cause overheating or damage.
12. Electric current that flows in only one direction (like batteries).
17. Electric current that changes direction repeatedly (like household electricity).

1. How much a material resists the flow of electric current, measured in ohms (Ω).
3. The movement of electric charge through a circuit, measured in amperes (amps, A).
4. A material that does not allow electricity to flow easily (like rubber, plastic, or glass).
6. A circuit that is broken, so current cannot flow.
7. The force (or pressure) that pushes electric current through a circuit, measured in volts (V).
8. Connecting an electrical circuit to the earth for safety.
11. A rule that shows the relationship between voltage, current, and resistance
13. The flow of electric charge (usually electrons) through a material.
14. A device that opens or closes a circuit to control electricity flow.
15. A closed path that allows current to flow.
16. A safety device that melts to break a circuit if the current is too high.
