Answer Key / Explanation : (d) -
|
(d) In a common-emitter configuration, the voltage gain is defined as the ratio of change in the output voltage to the change in the input voltage.
Also, power gain is defined as the ratio of the change in the output power to the change in input power.
Dividing Eq. (ii) by Eq. (i), we get
|
resistance gain …(i)
resistance gain …(ii)
