What is the purpose of using a fuse in circuits?
A fuse is used as a safety device to protect electrical circuits and appliances from damage caused by excessive current.
When the current in a circuit exceeds the safe limit due to overloading or a short circuit, the fuse wire heats up and melts, breaking the circuit. This stops the flow of current instantly.
The main purposes of a fuse are:
By interrupting the circuit during faults, a fuse acts as a protective barrier in electrical setups.
