- AHeating
- BMagnetic
- CChemical
- DNone of these
✓
Answer
- Heating
Explanation:
Electric fuse work on the principal of heating effect of current.
Fuse wire is a wire of high resistance and low melting point.
When very large current will pass through it, heat will be generated which will melt the fuse wire and break the circuit.
By using electric fuses in home we can protect the home appliances from damaging by large amount of current.
