Answer 2

Fuse acts as a circuit protection device.

Step by step explanation:

It is a current interrupting device which breaks the circuit by fusing the element when current in the circuit exceeds certain value.

• It protects the wiring and appliances if something goes wrong.
• It contains a piece of wire that melts easily.
• If the current is passes through a fuse with high voltage the wire is heat up until it melts and breaks the circuit.

Therefore, Fuse acts as a circuit protection device.
