williampowell (if still around, this is looking like a drive-by) you might notice no one has offered anything about how a fuse actually could make a difference. I only commented on the sound, not any reason for the sound.
The old school simple EE approach is wire is wire, electricity flows like water through a pipe, doesn't matter if its copper, PVC or ABS it's just a pipe. Resistance to flow is all that matters. In the pipe it's pressure, in the wire it's volts and ohms. They think they got it all nailed down.
But in reality it's not like that at all. In reality there is no flow, but rather a charge that propagates by fields. It's like when they do "the wave" in a stadium. The wave moves all the way around but the people doing the wave hardly move at all.
Music is electric fields doing the wave, only alternating back and forth very fast and all different amounts. The field is at least as important as the pipe or wire.
That is why for example there is a little blob of material on every Blue and Orange fuse.
You missed it, I will guarantee everyone missed it, but not me, being sharper than all of you put together I didn't miss it and so here it is:
That goo is a keeper too..
Scroll up and see I am not making this up. Those of us who know, we know. The rest of you, happy to share but you only learn when you're willing to learn. And an awful lot of you seem to be not very interested in learning.
