Question

During the installation of an electric circuit in the house, why do we use body earthing?

• A. To decrease the current flow in the electric circuit.
• B. To complete the path for current flow in the electric circuit.
• C. To protect us from electrical shocks.
• D. To increase the current flow in the electric circuit.

Answer 1

The correct option is C To protect us from electrical shocks.

Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the fault.
