There is a problem I have been dealing with for hours.
In my Electronic 1 lecture, small signal analysis was like this:
The small signal equivalent of this circuit in my lecture notes was this:
When they calculate the no load voltage gain Av they do not remove the Rc. To me, Rc is the load but they do not accept.
In this semester in Electronic 2 lecture, the topic is feedback of amplifier circuit and this time they accept Rc is load (effective load this time) and when they calculate the no load open-loop gain they remove the Rc.
Why? Which one is correct?
(I am sorry for my bad english)
