In an amplifier the load resistance 
is equal to the plate resistance 
. The voltage amplification is equal to
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Voltage gain or voltage amplification of an amplifier is given as 
Where 
is the amplification factor which is the negative ratio of change in plate voltage to the change in grid voltage. This factor is always greater than 1 and depends upon the relative distance between the plates.
is the plate resistance or the anode resistance
is the load resistance
So when load resistance 
is equal to the plate resistance
