A common emitter amplifier has a voltage gain of 50, an input impedance of 
and an output impedance of 
. The power gain of the amplifier is [2007]
Text Solution
Verified by ExpertsThe correct answer is:
C
AC power gain is the ratio of change in output power to the change in input power.
AC power gain
where 
is voltage gain and 
is AC current gain.
Also, 
Given, 
Hence, 
Now, AC power gain
