What does the fuse do?

1.The core of a fuse is a piece of wire with a low melting point, so the fuse itself conducts electricity.??A fuse is usually installed at the point where a circuit enters. When the circuit is switched on, current flows through the fuse and the load, and the load works properly.?

2.When the circuit is working properly, the current flowing through the fuse is not very high, and the fuse temperature is not very high.?

3.Because the fuse is connected in series to the incoming line of the circuit, as the load in the circuit increases, so does the current flowing through the fuse.?

??

4.The temperature of the fuse will rise as the current flowing through it increases.?

5.Because the fuse has a low melting point, when the fuse is too hot, it will melt and break, cutting off the current throughout the circuit.?

?

6.Without a fuse, the current throughout the circuit increases enough to burn out the load and even cause a fire.?
