What is an electric fuse and why is it important in electric circuits?

Understanding Electric Fuse

Electric Fuse: An electric fuse is a safety device that is designed to protect an electrical circuit from overcurrent. It is a thin piece of wire that is designed to melt and break the circuit when the current flowing through it exceeds a certain level.

Importance of Electric Fuse in Electric Circuits

An electric fuse is important in electric circuits because it helps to prevent damage to the circuit caused by excessive currents. When the current exceeds the rated value for the circuit, the fuse will melt, breaking the circuit and stopping the flow of electricity. This helps to protect the components of the circuit from damage and prevents the risk of electrical fires.

Placement in Electric Circuits

Live Wire: The electric fuse should be placed on the live wire in an electric circuit. Placing it on the neutral wire would not provide the necessary protection as the neutral wire carries the return current and does not pose the same risk of overload as the live wire.
