Question

Three amplifiers each with a voltage gain of 10 are connected in series , then overall amplification is ?​

Answer 1

If K is a gain of one stage

then total gain of n stages = (K)ⁿ=(10)³=1000

hope it helps you

Answer 2

Hey there !

• Whenever overall /total amplification

is asked in the question , you simply

have to multiply their values by the

number of amplifiers connected.

• So hence, in this question n= 3 and voltage gain = 10

So , overall amplification is

• n * voltage gain

= 3*10

= 30

Hope it helps!
