Role of capacitors in amplifier
The capacitor is an open circuit for the DC voltage/current from the previous stage, but it allows the higher frequency AC signal to pass to the next stage. If you remove the entry capacitor to a new stage, the DC voltage from the previous stage will displace the operating point of the new stage, which will not operate properly.
Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.
