Question

What is the colour of the insulation of, live wire

Answer 1

Insulation as its name suggests is used as a non-conductive material which acts as a protection around a metal wire. It also prevents the leakage of current from contact. There are mainly three types of wires used in electric circuits. That is, live wire, neutral wire and earth wire.

Complete step-by-step solution:
The live wire can be defined as the wire which is carrying the main current. This wire is supplying current to the electrical appliances used in households. In household purposes the maximum voltage carried by the wire is 220V which is an AC supply. Thus we can say that the 220V is used in the household wiring system. The colour of the insulation wire for live wire is

Note: The neutral wire usually carries the current away from the electrical appliances and thus it completes the circuit. In the case of a neutral wire a black insulation is used. The earth wire is used to ground or earth the current from the metallic part of the electronic devices, at zero potentials in the case of any leakage. Thus the earth wire has green insulation. Insulation as its name suggests is used as a non-conductive material which acts as a protection around a metal wire. It is generally made up of non conducting materials such as plastic or silk. The other insulating materials are clay, rubber etc. Thus it prevents the leakage of current from contact.
