Well I was just wondering how ohmic resistance works in a diode . I mean let's take forward bias mode.In forward bias mode electrons are diffused from the n type region to the p type region.The depletion layer still exists but is very narrow.So according to Drude model of ohmic resistance electrons bump into atoms of the resistor and lose all their momentum during the movement of them opposite of the battery voltage.But in a pn junction diode those atoms are basicly negatively charged because the boron atoms in the depletion layer are negatively charged . So how does this work?
