At the atomic and molecular level, why exactly does a resistor give off heat?
I'm trying to understand the fundamental science acting behind this device.
I read that when treated like water, forcing water through a bottleneck creates increased pressure on the smaller diameter pipe which translates to heat in the real world. But why??
From my perspecive at the atomic level the valence electrons should simply 'bunch up' like in a funnel or pipette waiting to reach the nozzle. Why must the water or current flow at the same 'rate' as in the larger diameter pipe?
