1.	The total gain of a multistage amplifier is less than the product of the gains of individual stages due to ___________(a) Power loss in the coupling device(b) Loading effect of the next stage(c) The use of many transistors(d) The use of many capacitorsThe question was posed to me during a job interview.My question is taken from Multistage Amplifier topic in portion Differential and Multistage Amplifiers of Electronic Devices & Circuits
Answer» The correct answer is (b) Loading EFFECT of the next stage The best explanation: The output of first amplifier stage is the input to next stage. In this way OVERALL VOLTAGE gain can be increased, when NUMBER of amplifier stage is used in succession, it is called a multistage amplifier. The load of first amplifier is the input resistance of the second amplifier. Thus overall gain is reduced.
