in given fig. each network have voltage gain 1/2 then voltage gain of cascaded is (a)1/4 (b) 1/5 (c)1/6 (d)1 select correct option. answer provided is 1/5 ,any one can explain how 1/5 is correct
No, the gain is equal 1/5 because the load effect.
Second network load the first, and that is why the gain is drop to 1/5.
The output voltage of a first network will be 2/5
