I am noob,still learning the basics,right now I am trying to understand how Darlington transistor pair works.Its probably simplest thing in electrical engineering after two resistor voltage divider yet I cant understand it.Specificaly I am looking at live graphical animation in the preset of falstad free online circuit builder and simulator.
I am looking how the current is flowing through it,how the voltage is at various points.The specific question I have is,why is the voltage and current at the base of the second transistor so low? I mean the transistor that is little bit lower and on right side,considering there is 5V voltage source and single 300 ohm resistor before it,I would expect the base current and voltage be higher.
Almost all the energy goes collector > emiter but very little through base > emiter.I am assuming that both collector > emiter and base > emiter resistance is zero,I know this is not the case in real world,but this is extremly primitive idealized simulator,I dont see anywhere shown that there are any resistances in this bipolar transistor,it acts like there is voltage divider thing going on between base collector and emiter.
I would think that the first higher left side transistor have zero collector > emiter resistance and voltage drop,I imagined that the voltage at the base of the second lower transistor should be just as high as voltage at its collector,most transistors I read datasheets would blow up becose they cant handle anywhere near as much voltage at their base as they can on collector.
EDIT: I made mistake,I mean why is the current higher,not voltage.
