niho identification and function of live wire​

Answer 1

Explanation:

• Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the fault.
• Live wire is the only wire which contains electricity. The electric current comes from the live wire. ... The current comes through the live wire and flows back from the neutral wire. At times there are earth wire, which are wires connected to the deep earth with a metal.
