unless it's some weird kind of resistor that doesn't obey the normal laws...yes

Twinkle twinkle little star,
power equals I squared R

so am i correct in assuming that if the resistor has 190C/min flowing through it and a resistance of 2kOhms, then i would do:

190^2 *2000 and get 72200000 watts?

current should be in Coulombs per second (otherwise known as the Ampere)

So divide your C/min by 60 before you square it.

Coulomb is Charge, which is Q. You have to convert your charge per time unit to amperes before you can plug it into ohm's law.
