Question

Write the names of the wires used in the domestic electrical circuit and also write the colours of the insulating wires.

Hint:

Always check the colour coding of wires before handling them to ensure safety and proper connection in circuits.

Answer 1

In a domestic electrical circuit, three types of wires are used:
Live wire: The wire that carries current to the load. It is usually coloured red or brown.
Neutral wire: The wire that completes the circuit by carrying current away from the load. It is coloured blue.
Earth wire: This wire provides safety by carrying current directly to the ground in case of a fault. It is coloured green or yellow-green.
