I have a question that has been bugging me for a while now. I would think that since each FET circuit is basically independent of the other that once I blew out some and disconnected them, I would still turn the dial on my pot to the same place and just get proportionately less current running through the system. For example, if I had to turn it 3/4 on when all 10 FETs were working to get 47 amps and I would think that now that I only have 8 FETs if I turned it 3/4 of the way I would get 8/10ths of 47 amps, or 37.6, but it doesn't seem to be working that way. I only have to turn it barely on and it starts to go up fast. If I were to turn it 3/4 of the way on now, it would be above 47 amps, so I don't do that. Is this behavior to be expected, or is there something wrong?
