[Drop amps from 25A to 8A]

See told you it was me. I misread the thing about the schematic.  :) I'll post one as soon as I have one.

[Drop amps from 25A to 8A]

Thanks for the reply, I guess my math was wrong. I was using P = V squared / R which would be 13.8 squared (190.44) / 1 = 190.44W. Yes, I want to limit the maximum amperage running through so that it doesn't get all the way up to 25A. Having a way to vary the max amps would be really nice. I'm currently experimenting with Peltier modules and I don't want to fry it by putting too much amperage through it. It's probably just me, but I don't see any link to a schematic that would limit the amps to 8.

[Drop amps from 25A to 8A]

I have a 13.8V / 25A power supply that I would like to use in testing. I'm looking to drop the amps from 25A to around 8A while keeping as much voltage as possible. I've thought about using a resisitor, but it would have to be in the neighborhood of a 200W / 1.725 ohm resistor to work. Any suggestions on how to pull this off without needing a huge resistor?

Thanks in advance.
