Question

Name two safety measures commonly used in electric circuits and appliances.

Answer 1

Hint:To solve this question we should keep in mind the are the risk we face when we use electric circuit:
Contact with live parts, which can cause shock and burns, is one of the most dangerous aspects of electricity. Electricity could be the source of ignition in a potentially flammable or explosive setting, such as in a spray paint booth, resulting in a fire or explosion.
So, we will answer it keeping in mind all these facts.


Complete step by step solution:
Two safety measures commonly used in electric circuits and appliances are:
1. Electric Fuse:
A series connection is made with an electric fuse. It avoids short-circuiting and protects the circuit from overloading.
The electric fuse prevents excessive current from flowing through the circuit.
When the current flowing through the wire exceeds the fuse element's maximum limit, the fuse melts, interrupting current flow and protecting the appliances connected to the circuit.
2. Proper earthing:
An all-electric circuit that is properly earthed so that any current leakage in an electric device is transmitted to the ground and individuals using the appliance do not receive a shock.
To avoid electric shocks, earthing is required.
Any current leakage in an electric device is transported to the earth, and the individuals who use the item are not shocked.

Note:
A fuse is a type of electrical safety device that can protect an electric circuit against excessive current flow. It is intended to enable current to flow through the circuit, but if the current surpasses a certain limit, it will open, cutting the circuit.
