For a pulsed-power application, that puts maybe 100A through a 5m-ohm resistor for several tens of milliseconds, how in heck do you figure out the resistor size?
I'm looking at data sheets, and I'm seeing power ratings but no sort of pulse energy rating. Is this because it just ain't done, because the resistors I'm looking at aren't hoity-toity enough, or because it's just something that you know?
At any rate, it's something like one Joule every ten seconds, so a 1/10th watt resistor should be just fine -- right? Or should I try to estimate the heat capacity of the part, and get myself all confused by thermodynamics?
