What term describes a fuse that has melted?

• A. Shot
• B. Done
• C. Blown
• D. Tripped

Answer: (C)

A fuse that has melted is referred to as "blown." This term is used because when a fuse experiences an overload or fault current, it heats up to the point where its element melts, thereby interrupting the electrical circuit. This process is a safety mechanism, preventing excessive current from flowing through the circuit and potentially causing damage or a fire. The blown fuse needs to be replaced for the circuit to function again, which is why understanding this terminology is essential for maintenance and repair tasks in electrical systems. The other terms provided do not accurately convey the concept of a fuse melting due to electrical overload.
