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%.
