i know that it is not as simpls as a bulb, i said so to just give an example.
the resistance change due to temperature difference was negligible only if the temperature difference is very small. if your cpu as standard temp and voltage has a temp of for example 50degrees C, and when overclocked the temp remained 50degrees C, or changed to somewhere near 50 degrees C, then you can ignore the difference in resistance, otherwise you cannot.
to find the exact amout of heat dissipated, you need to find the VI graph of the cpu core material.
