Hellow guys!
I find this concept really confusing, if the bulk resistance of a diode is an approximation of the I-V characteristic curve for a diode, Why then is that bulk resistance compared to ac resistances of the same diode at a particular operating in calculated values, seem not to be approximation of one another at all..
Example, there was a solved problem, whose answers of bulk and ac resistances where 1 ohm and 26.53 Ohms, can this really mean approximation. What I use to believe, resistance values don't depend on whether the source is A DC or AC..
Can someone prove me wrong pleaseee!
