Reflecting on the Inverse Relationship between Fuse Wire Rating and Thickness

What is the relationship between the rating of a fuse wire and its thickness?

Why is the fuse wire rated at 5A likely to be thicker than the one rated at 10A?

Answer:

The fuse wire rated at 5A is likely to be thicker than the one rated at 10A.

Explanation: In the context of electrical wires, such as fuse wires, the thickness of the wire is inversely proportional to its rated current or amperage (A). In other words, the wire with a lower rated current is typically thicker. Fuse wires are designed in this way to ensure safety by melting when the current exceeds their rated capacity, with thicker wires able to handle lower amounts of current without melting. Therefore, the 5A fuse wire is likely to be thicker than the 10A fuse wire.
