Your sample is adequate. Maybe I was too narrow in my thinking. Fuse wire can fail under many different conditions and when I wrote earlier, I was thinking in very simplistic terms. I was simply thinking of an ideal situation with a perfect resistance wire brought somewhat slowly, maybe over...
Why does fuse wire always melt in the middle.
First, it doesn't always melt in the middle but you're observation is generally correct. If we can assume that the thermal mass of the connection points on either side of the fuse wire are the same and there is REASONABLE thermal equilibrium in the...
