What Role Does The Fuse Play In The Circuit

A fuse is an insurance policy that burns wires to prevent too much electricity. In fact, the fuse is a kind of easy to burn fine alloy wire, it can only pass through the normal electric current, when the electrical flow exceeds a certain value, it will heat and fuse and cut off the power supply, so as to protect the wire from burnout, especially when the wire short circuit, such as not quickly cut off the power supply, the wire in an instant will be In general, fuses play a protective role. If a fuse is set up here, the fuse will fuse and cut off the current when the current is abnormally elevated to a certain height and heat, thus playing the role of protecting the circuit safe operation.
