Question

Why is a fuse always connected in the live wire of the circuit?

Answer 1

Fuse connected in the circuit's live wire:

1. It is understood that the overloading in the circuit can damage the connected device.
2. Whenever there is overloading in the circuit, the fuse wire melts because it is made up of high resistance material. As a result, the circuit breaks and the flow of current stops to prevent the device from being damaged.

Therefore, the fuse wire is used in the circuit to prevent the device from being damaged.
