[TriEmbed] Dummy Load

Any reason I could use something like this 200W rheostat to act as a test
dummy load?

I'd need 25A or so... so, dial it down to 0.2 ohm. And at it's max (5A) it
should draw 1A.
People always talk about constant current loads... but I'm testing a
constant voltage so I believe what I really need to be varying is the
resistance...
