If the control voltage is 10 volts, then a 10k potentiometer would
dissipate 10v*10v/10000ohm = 0.01 watts. You do not need a 2 watt 10k pot.


The two watt pots are made for long life, and have lower wiper noise
that the cheap crap. They were used as volume controls in military
radios and other electronic equipment in WW-II, and are still good.

Buy cheap crap if you want to, but cheap pots are a foolish
investment.
