I am finding it difficult to understand how exactly this works and would appreciate any help.
From my understanding:
The emitter base junction has to be in forward bias meaning that Vb is more positive than Ve ( ie Vb>Ve ?)
The base collector junction has to be in reverse bias hence Vc is more positive than Vb ( Vc>Vb ?)
From what I know current should go in from the emitter then through P-type and if it is thin enough it would reach the collector. Here the currents seem to be in opposite directions and I cant make much off it.
I understand the P-n junction theory between holes and electrons and how this can be seen as 2 back to back diodes however I am finding it difficult to analyse exactly how it works from the very start.
If we where to start straight from the begging where current flows from the cells how would it work?
I would appreciate the help. Many thanks.
