hjams, I am quite confused. Here is my doubt:
For a voltage divider biased circuit( CE config), the operating point doesnot change with the addition of load to the collector and ground. How is it possible? Addition of load should alter the collector current, Vce
and voltage drops across Rc, Re, theoretically.
What I think is , if we donot want to change the operating point, then the load impedence should be very high when compared with the source impedence.(Here the source impedence is the output impedence of the BJT).
Am I right?
If so, how will we know, what load value we can use, for a any biased BJT ?
Is there any calculation?
