What are fuses used for?


I have, I’m sure to many, a very dumb question. I keep reading about fuses.  I have a fairly sophisticated system and have never come across the need for a fuse.
Can someone tell me where these fuses go and what they’re used for?

Could a fuse make a difference? I doubt it, but there's good ways to tell.

Put an oscilloscope on both ends of a fuse, ideally something with a frequency analyzier. Look at the scope.

When anyone provides visible proof of a fuse in anyway showing a voltage differential in real time between the input and output I'll be interested.

Now, that's not to say you could not do something cool, like have a fuse with a built in ferrite bead or something, which would reduce EMI / RFI. Would it be audible? See above. :)

Great idea. Why don’t you do it and report your findings? Are you waiting for someone else to do it?
I'm definitely not about to take work assigned by you, George.

I have no particular interest in fuses, I was merely pointing out that if audiophile fuses do anything at all the effects would be super easy to measure at the fuse itself.

If I was going to sell an expensive gadget that actually did something I'd be jumping at the chance to prove it's efficacy.
