A fuse is always connected in the live wire of the circuit. Explain the reason.
I Types Of Wires:
Generally, in order to complete the circuit, there should be a wire that can carry current to the appliance and one that helps the circuit to be completed and the third wire that helps to prevent the leakage of current.
The wires that are used in an appliance are:
- Live Wire - Red insulation
- Neutral Wire - Black insulation
- Earth Wire - Green Insulation
Answer and Explanation:
A fuse wire is a safety device that prevents the damage of the electric appliance and during the\is time when there is an abrupt supply of current in the circuit. the fuse wire melts and breaks the connection of circuit with the appliance
The fuse wire must be connected in series with the appliance and to the live wire because live wire carries current to the appliance and in case of any emergency situation the current must be stopped hence current in the live wire must be stopped.
After the fuse wire melts the current in the circuit is stopped and thereby causing no damage to the circuit hence the fuse wire must be connected to the live wire.
