Name two safety measures commonly used in electric circuits and appliances.
(N/A) Two safety measures commonly used in electric circuits and appliances are as follows:
$(i)$ Electric Fuse: Each circuit must be connected with an electric fuse. This prevents the flow of excessive current through the circuit. When the current passing through the wire exceeds the maximum limit of the fuse element, the fuse melts to stop the flow of current, thereby protecting the appliances.
$(ii)$ Earthing: Earthing is essential to prevent electric shocks. Any leakage of current in an electric appliance is transferred to the ground, ensuring that people using the appliance do not receive a shock.
