Hi Gaurav,
Sorry for the late response.
First of all you should know that the common-collector configuration of the transistor is hardly found in the electronic circuits, since it is not that practical to implement. Hence it is only a theoritical circuits and your observations are absolutely correct.
My answer is that the “circuit is not practical”. That dosen’t means the Boylestad is wrong, they have given you the simplest form of common collector circuit so that you can understand the working of different configuration of transistors.
I’ve seen in lot of text books the last line of the circuit description as “this circuit is not practical to implement”. Is it mentioned same in the Boylestad also??
Lot of adjustments need to be done with common-collector circuit to get it working.
For the time being you can just learn the theory and the present circuit for the exam purpose.
It would be great if you try out a common-collector circuit in your lab.
May I know your other doubts.
