Across
- 3. This metal is commonly used as a conducting material in electrical wiring due to its excellent conductivity.
- 4. A material through which electric charge cannot flow easily.
- 5. A device that automatically stops the flow of electricity in a circuit when there is an overload or short circuit.
- 8. This occurs when electrical components exceed their safe operating temperature, potentially leading to damage or fire hazards.
- 9. This wire provides a safe path for electrical current to the ground in case of a fault.
- 10. This wire completes the circuit by carrying current back to the power source.
- 12. This occurs when too many devices are connected to a single electrical circuit, causing excessive current and potential hazards.
- 14. This wire carries the high voltage from the power supply to the appliance.
- 15. An electrical connection that allows current to return to the source by bypassing the intended path, potentially causing a hazard
- 16. A thin wire that melt if large current flow
Down
- 1. A fuse with this rating is suitable for appliances with a power output of up to about 900 watts, when used with a 230V supply, such as lamps or low-power devices.
- 2. A safety feature where two layers of insulation are used to protect the user from electric shock, often eliminating the need for an earth wire.
- 6. An electrical hazard caused by broken or exposed wiring.
- 7. This common type of plastic is used as insulation for electrical wires due to its durability and resistance to heat and chemicals.
- 11. An electrical appliance housing that requires grounding to prevent electric shock.
- 13. Connecting electrical appliances and circuits to the ground to prevent electric shock and ensure safety.
