Question

What is the importance of live wire?

Answer 1

Hint: Here, we have been asked about the live wire. First we have to understand the concept of live wire, meaning, importance and use in the electrical circuit then we will be able to understand how it is represented in the circuit.

Complete answer:
Live wire is the wire that is active for carrying current in the circuit. This live wire is also known as the hot wire. To indicate the live wire the colors that are to be used is Red and Brown. This live wire is the wire that conducts current through the devices.

A live wire is the wire which carries current to the device. When there is something wrong inside the device or circuit and the live wire occurs to get connected to some metal part, the circuit breaker will blow to protect the user from irrelevant sensation or electrocution.

When a live wire comes into contact with a neutral wire the resistance of the circuit falls with drastic change and there will be a large amount of current flow in the circuit.A short circuit can happen due to the disruption of insulation of the wires or water forming the contact between the live wire and neutral wire. The large current generation causes fire in the circuit. Hence, we have discussed the importance of the live wire.

Note: Insulation is the protection on any current carrying wire of the non-conducting material. Polyvinyl is used on the wire to provide insulation between two conducting surfaces. Neutral wire brings the circuit to a ground state or bus bar usually connected at the panel of electrical conduction in the circuit.
