Detailed Solution

Concept: In order to protect either the load or the source of the circuit against overcurrent, fuses often include low resistance resistors.
It does not permit excessive current or raise the circuit's resistance. As a result, the circuit's resistance is never increased, and a large current is not permitted. Because it prevents excessive current from flowing through the circuit, it also shields gadgets from heating.
To prevent overcurrent from travelling through the circuit, fuses are always linked in series with the circuit along the electrical components. When a fuse blows, the entire circuit cuts off current to the electrical components. If the fuse were connected in series with the circuit, no other branches' current would be impacted. It regulates how much current flows via a circuit.
The fuse is an electrical safety device built around a conductive strip that is intended to melt and separate in the case of an excessive current, therefore we should be aware of that and its properties.
Hence, the correct option is 1 .
