In a transistor in common-emitter configuration, the ratio of power gain to voltage gain is
Text solutionVerified
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.
resistance gain .....(i)
Also, power gain is defined as the ratio of the change in the output power to the change in input power.
resistance gain....(ii)
Dividing Eq. (ii) by Eq. (i), we get
