Dear damarlasumanjali@gmail.com
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
The derivation of voltage gain for transistor as an amplifier can be found as is in the textbook.
Kindly refer to NCERT-XII-Part II textbook page numbers 497 and 498 for the same.
If however, you have doubt about certain step in the derivation, then you may post it on our site. We will be happy to help you.
The application of these formulae is simply to identify by how much that transistor can amplify the nput signal. It can be used in any device like loudspeaker, radio, etc where amplification is needed.
