What is a fuse and how is it connected in an electric circuit?

A fuse is a device that protects a circuit from excessive current. It is made of a wire with a low melting point that breaks when the current exceeds the rated value. Fuses are connected in series with the circuit they are protecting.

How a Fuse is Connected in an Electric Circuit

A fuse is connected in series with the circuit it is protecting. It is usually connected at a point where the current enters the circuit. When the current exceeds the rated value, the wire in the fuse heats up and breaks, interrupting the flow of current. This disconnects the faulty circuit from the power source, preventing damage to the rest of the circuit.
