A. Danger of electric shockB. Voltage fluctuationC. OverloadingD. High temperature of the conductorsAnswer: A. Danger of electric shockExplanation: 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.
Purpose of Earthing:- To save human life from the danger of electrical shock or death by blowing a fuse. It provides an alternative path for the fault current to flow so that it will not endanger the user.
- To protect buildings, machinery & appliances under fault conditions i.e., to ensure that all exposed conductive parts do not reach a dangerous potential.
- To provide a safe path to dissipate lightning and short circuit currents.
- To provide protection against static electricity from friction.
