The resistance reading across a good fuse would be?

• A. Infinite ohms
• B. 0 ohms
• C. 5 ohms
• D. 10 ohms

Answer: (B)

A good fuse is designed to allow electrical current to flow through it without any interruption, providing a closed circuit. Therefore, when measuring the resistance across a functioning fuse with a multimeter, the reading should ideally be 0 ohms. This indicates that there is no resistance to the flow of electricity, affirming that the fuse is intact and operational. In contrast, if the fuse were to blow or fail, it would create an open circuit, resulting in an infinite resistance reading, as no current could pass through. Therefore, the expectation of finding 0 ohms across a good fuse aligns with its purpose of facilitating electrical flow without resistance.
