What is the importance of live wire?

The live wire carries the current to the appliance. The live wire is also called hot wire. Live wire is brown or red in colour. This is the wire through which the current enters an appliance.

Explanation

  • A live wire is a wire carrying an electric current. If something goes wrong inside the machinery or circuit and the live wire gets accidentally connected to some metal part, the circuit breaker will blow, protecting the user from an unpleasant sensation or even electrocution.
  • When a live wire comes in contact with a neutral wire the resistance of the circuits fall drastically & a large amount of current flows in the circuit.
  • A short circuit can be caused due to the breaking of insulation of the wires or water forming the contact between the live wire & neutral wire. The large current generated can cause a fire.
