Hello, I have been looking this thing up for a couple hours now on google and textbooks. So far, I got nothing... When you use a fuse wire in a circuit, why does the fuse wire always melt in the middle? I don't see how the middle of the fuse wire gets hotter than the ends unless the middle of the fuse wire is thinner than the ends. Which I don't think is the case. Well, time to ask the experts. Thanks.
