so, I've realized that all the fuses out there, are all
amperage-dependent fuses. there are some very very rare
voltage-dependent "fuses," but otherwise, I don't know any fuse that is voltage-dependent. I'm not exactly a genius, so... I need a little help. this could very well be a stupid, dumb, and expensive idea, but I'm just a little curious.
let's say I have a Tungsten wire. it is 0.8mm thick, and 10mm long. The ambient temp is 45°F.
if the wire is conducting a voltage of say, 24V at 2.5A, it should generate a temp of
at least 90°F on the wires.
here is my plan:
1)
I will put two tungsten wires close together, but not touching.
2)
next, I will drip about 0.025mL of Gallium, joining the two wires.
3)
now, when a voltage of like 24V flows through, the high resistance of the tungsten heats the wires up. since Gallium melts at just 87°F, when the wires heat, the Gallium will melt, thus breaking the connection
What do you guys think? is it kinda dumb? or is it worth a try?
[EDIT] So, I guess the conclusion is that this was a stupid idea
