Question
A fuse is always connected in the live wire of the circuit. Explain the reason.
Solution 1
The fuse wire is always connected in the live wire of the circuit because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire. Now if a person touches the appliance, he may get a shock as the person will come in contact with the live wire through the appliance.
Solution 2
Always put the fuse into the appliance's live wire at the beginning of the circuit. When the fuse melts, it will break the connection and save the circuit.
