A short circuit can damage a circuit in a very short time. But stopping it can be very simple.
In a basic circuit, the lamp has an important job. It slows down the current.
If we remove the lamp, nothing is left to slow it down. The current goes very high. This is a short circuit.
To stop it, we add a fuse. Inside the fuse there is a thin metal wire. When the current goes too high, the wire burns and cuts the circuit.
And that is how a simple fuse protects your circuit.
