The table also illustrates that for higher value resistors you reach the voltage limit before the power disspation limit. Exactly where that happens depends on the voltage and power rating of the resistor. Given by inverting Terry's formula, R = (V^2)/P
Terry's formula above is a touch ambiguous since it's not clear that the square root applies to the product of power and resistance rather than power alone. I appreciate that it's not possible in ordinary characters to extend the top bar of the root symbol to make this clear. V = √(PR) might be better.
