I'm looking for a way to make a .01 Ohm resistor for a circuit I'm building. The current in the resistor will max out at 10 amps, but there will be times when it runs 10 amps continuously. This resistor will be potted in silicone and I can't really put a heatsink on it, though I can put the resistor in a spot where it's in contact with the circuit enclosure.
I took out my trusty milliohmmeter and measured the resistance of .030" steel baling wire, but the resistance of that kind of steel seems so climb significantly with heating. I can't have this resistor varying by much more than 1 or 2%.
