Two amplifiers are connected one after the other in series (Cascade). The first amplifier has a voltage gain 10 and the second has a voltage gain of 20. If the input signal is 
V. the out ac signal will be
Text Solution
Verified by ExpertsThe correct answer is:
C
For amplifiers connected in cascade, the overall voltage gain is the product of individual gains.
Given input signal:
Output signal:
