Two safety measures commonly used in electric circuits and appliances are:
An electric fuse is connected in series. It protects the circuit from overloading and prevents it from short-circuiting.
- The electric fuse 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 current flow through that circuit, hence protecting the appliances connected to the circuit.
Proper earthing of an all-electric circuit in which any leakage of current in an electric appliance is transferred to the ground, and people using the appliance does not get the shock.
- Earthing is a must to prevent electric shocks.
- Any leakage of current in an electric appliance is transferred to the ground, and people using the appliance do not get the shock.
