Understanding Fuse in Electric Circuits

The Material Used in Fuse Wires

Fuse wires are typically made of:

  • Lead
  • Tin
  • Copper

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.
