WebJan 27, 2024 · If I have an NPN transistor and let's say we set the base voltage higher than the collector voltage.(Emitter is connected to GND).There are 2 currents flowing in the base because we have two forward biased junctions inside the diode , 1 is the current flowing from emitter to base and 1 is the current flowing from collector to base. WebWhen the npn transistor is not connected to circuit, the depletion region of both the p-n junctions is of the same length. But when we connect it to circuit, 2 things happen -. (1) Due to reverse biasing in upper p-n junction, the length of depletion layer increases. (2) Due to forward biasing in lower p-n junction, the length of depletion ... http://faculty.cord.edu/luther/physics225/Handouts/transistors_handout.pdf hide your crying eyes
