List the colours of the three wires in the cable connected to the plug of an electric iron.
The colours of three wires in a cable connected to the plug of an electric iron are:
(a) Live wire - red
(b) Neutral wire - black
(c) Earth wire - green
Explanation
The electric wiring in houses, shops, or factories has three wires: live, neutral and earth. The first two carry electric current from the power station and the third is earthed by connecting it to the earth through a metal wire called 'Earth Wire'.
To avoid confusion between these three wires, we follow different colour code to insulate these wires. This colour coding of wires helps us to connect the switches, plugs and other electrical components through the appropriate wire in the home wiring circuit.
The red wire is the live wire, the black wire is neutral and the earth wire is given green insulation.
