Final answer:
The correct answer to the question is b) Larger, circuit. A fuse with a low melting point metal strip breaks the circuit when overheated, serving as a crucial safety feature.
Step-by-step explanation:
Never replace a fuse with a larger fuse; always use the right circuit! The correct answer is b) Larger, circuit. A fuse is a safety device containing a metal strip with a low melting point. When a current higher than what the circuit is designed to handle passes through, the fuse heats up and the metal strip melts, breaking the circuit and preventing potential damage to the electrical system or fire hazards. Replacing a fuse with one that has a higher capacity can allow too much current to flow, posing a significant risk to the circuitry and safety.
