Transistor Amplifier

Question
16 out of 24
 

What is the effect of coupling capacitor on voltage gain of an amplifier?

At mid-frequency and high frequency, capacitive reactance of coupling capacitor is very small and coupling capacitor behaves as short circuit. At low frequency, capacitive reactance of coupling capacitor has significant value and some voltage drops across them and voltage gain is reduced.
