Red Coloured Insulated Copper Wire in Domestic Electric Circuits

Introduction:
In domestic electric circuits, various wires are used to carry electrical current safely and efficiently. One of these wires is the red coloured insulated copper wire. This wire serves a specific purpose in the circuit and is known as the live wire.

Explanation:
1. Live Wire: The red coloured insulated copper wire is called the live wire in domestic electric circuits. It is responsible for carrying the electrical current from the power source, such as the electrical panel or mains, to the appliances and devices connected in the circuit. The live wire is usually connected to the fuse or circuit breaker and is the wire through which the electric current flows.

2. Function: The main function of the live wire is to provide power to the electrical appliances and devices. It carries the alternating current (AC) or direct current (DC) from the power source, delivering the necessary voltage and current required for the operation of the appliances.

3. Insulation: The red colour of the insulated copper wire signifies that it is the live wire. The insulation is important to prevent any contact or accidental touch with the live wire, which could result in electric shock or other electrical hazards. The insulation material used is typically PVC (Polyvinyl Chloride), which is a durable and non-conductive material.

4. Identification: The colour coding system is used to identify different wires in domestic electric circuits. In this system, red colour is assigned to the live wire, black or blue colour is assigned to the neutral wire, green or green/yellow colour is assigned to the earthing wire, and other colours may be used for different purposes. This colour coding helps electricians and individuals to identify and connect the wires correctly during installation or maintenance.

Conclusion:
The red coloured insulated copper wire in domestic electric circuits is known as the live wire. It carries the electrical current from the power source to the appliances and devices. The red colour signifies its purpose and helps in identifying and connecting the wire correctly. It is important to handle live wires with caution and always follow safety guidelines to prevent any electrical accidents.
