Assertion: To avoid risk of electrical shock, the metal body of electric appliances is earthed.
Reason: Earthing saves us from electrical shocks.
✓

Answer

  1. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

Explanation:

To avoid the risk of electric shock metal body of an electric appliances is earthed. This is used as safety measure especially for those appliance that have metallic body for example electric iron, toaster etc. The metallic body is connected to low resistance conducting path for current.
