>So effectively, that resistor is dissipating 0.31 watts normally and so you need at least a 1/2 watt resistor?
That is correct and thanks to Don for such a good explanation.
Might I add that it is common practice that components are generally de-rated in use so as not to run them at or near the max. If a 50% de-rating is used then a 1W resistor would be desired.
