I was cleaning up today and came across an old dummy load I had that looks
like it is made from 2 watt resistors. ITs mounted on a quart size paint can
lid and looks to be a 50 watts worth of resistors. This looks like it may
have been a commercially built unit and I was wondering what the power
handling capability would be if the resistors were submerged in mineral oil.

Hi Jimmie, It would probably take a kilowatt, the question is for how
long? I was looking at my old Heath "Cantenna" manual and it says it
will take 1000 watts for about 1 minute in mineral oil. The resistor
element appears to be ~50-100 watts. The Cantenna is in a gallon paint
can. If none of the 25 resistors "fuse" out due to current, your load
should take a kilowatt for at least 15 seconds, and take 100 watts
~forever.
