"Web8. Power is P = I V. You can only relate it to resistance if you decided to fix one and replace the other by Ohm's law. Ohm's law states that voltage across a resistor is linearly proportional to the current flowing through it, or V = I R. This can be arranged to say that current is inversely proportional to voltage, or I = V R. " - Heat and power relation formula
