Which description best defines earthing?

• A. An object connected to the Earth by a conductor so that electric charges can flow between it and the Earth.
• B. A device that stores electrical energy.
• C. A type of circuit breaker.
• D. A method of increasing resistance.

Answer: (A)

Earthing is providing a direct path for electric charges to flow between a connected object and the Earth. By tying the object to the ground with a conductor, any fault current (for example if a live conductor touches a metal case) can flow away safely into the earth. This keeps the object's surface at or near Earth potential and helps protective devices like fuses or circuit breakers sense the fault and cut off the current quickly, reducing the risk of electric shock or fire. It’s not about storing energy, it’s not a device that stores energy, and it doesn’t increase resistance; it’s about offering a low-resistance route to the ground so faults are cleared safely.
