Across
- 4. a complete circular path that electricity flows through
- 8. a source of light caused by heating the filament
- 9. a negatively charged subatomic particle that can be either bound to an atom or free
- 11. a material in which electric current does not flow freely
- 13. a safety measure to prevent a house fire or an electric shock if there is excess electricity in the wiring system
- 15. a circuit in which the path is complete and there is a flow of current in the entire path, also known as closed.
Down
- 1. a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space
- 2. The ground-fault circuit interrupter is a fast-acting circuit breaker designed to shut off electric power in the event of a ground-fault within as little as 1/40 of a second.
- 3. an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit
- 5. an object or type of material that allows the flow of charge (electric current) in one or more directions
- 6. a circuit where the path has been interrupted or "opened" at some point so that current will not flow, also known as broken or incomplete
- 7. circuit where all circuit elements are arranged in a single path
- 10. an electrical path that branches so that the current divides and only part of it flows through any branch
- 12. an electrical component that can disconnect or connect the conducting path in an electrical
- 14. light-emitting diode; a semiconductor device that emits infrared or visible light when charged with an electric current
