I can immediately tell what you need stuffed into yours, asswipe.
Tell us, oh guru of mouthyness, what is it that generates the heat in a conductor. Do not merely say "current", tell us what the physical mechanism is that causes the medium to rise in temperature.
In steel transformer cores, they have constant pole reversals generating heat via hysteresis. What is the mechanism in electron flow through a conductor or semiconductor?
Then, in your infinite wisdom, tell us why fluctuations can be detected in the signal flows through such mediums as conductors, or ANY medium for that matter.
Or could it be that you did not foresee that such fluctuations do occur?
It appears that YOU are the shot noise of the group, fluctuation boy.
