From what I understand, a typical fuse wire will melt once it's current rating is breached by some factor.
However, a fuse also has a voltage rating, which signifies its dielectric strength. From what I've read, this voltage rating means that, "beyond this particular voltage, the fuse may conduct electricity even if the current being drawn is much much higher".
Does this mean that 1A @ 5V and 1A @ 100V builds the same amount of heat in a fuse wire? It shouldn't theoretically since the power rating
P=VI is way different, right? To put it in another way, can I use a 1A @ 220V fuse in an environment of 1A @ 5V?
