What is the use of earthing wire?
Advertisements
उत्तर
- Earthing wire is used to protect one from an electric shock.
- It does this by providing a path for a fault current to flow to the earth.
- It also causes the protective device (fuse) to switch off the electric current to the circuit that has the fault.
