Electrical Fuse
Key Stage 4
Meaning
A fuse is an electrical component which prevents very large currents in a circuit.
About Fuses
- Fuses are a thin piece of wire which is designed to melt when the current through the wire is too large.
- Fuses are found inside plugs and are used to reduce the risk caused by a power surge.
- The live wire is connected to a fuse in the plug so that if too much current goes through it into an appliance the fuse will break and stop the current.
This diagram of a plug shows the location of the fuse. |
