The capacitor is used to block DC bias from the output, so that only the AC signal is passed. In an audio amplifier, for instance, unwanted DC in the output would cause distortion when fed to a speaker, or could even damage the speaker or amplifier.
In the case of interstage capacitors, they block DC so that the output of the first stage does not affect the bias of the second stage.

What is an unbiased transistor?
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.

What is difference between transistor and amplifier?
A transistor is an electronic component. By itself it has little use. An amplifier is a complete, functional circuit, generally made up of several components. A transistor can be a component part of an amplifier, however an amplifier may be constructed without any transistors (using vacuum tubes instead, for instance).
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
Basic theory of two stage RC coupled amplifiers?
connections are to be made per the crkt the main of this crkt is to make strong or to bost the signal comming to the crkt input is given with ac supply and they are connected to resistor and capacitor when the ac suppply is given it contains slight amount of dc supply so to block the dc supply capacitor is used and the dc supply is given at the collector so that resistor present at c and ground gets biased then another capacitor used at c to ground for removing the dc supply then out put seen on cro across collector to ground we get the perfect amplified signal the more we give the coupled amplifer the most amplfed sgnal we get
Is paper capacitor use in transistor amplifier?
It can be, but may not be required. Capacitors are used for biasing purposes, to remove DC from inputs, and for filtering in amplifier circuits (just to name a few).
Why you use coupling capacitor in electronic amplifier?
It is used to couple output of one stage to input of next stage
What is an unbiased transistor?

Can you use semiconductor as a capacitor?
Transistor either increases or decreases current.. Capacitor stores energy

Main use of a Common collector transistor amplifier is?
No voltage gain
What is use of bipolar junction transistor?
amplifier, switch, oscillator, etc.
Why you do not use capacitor in a transistor as switch?
The capacitor is there to block any dc voltage that might be applied to the input terminal, which could cause damage or upset the biassing if it was allowed through to the base.
Why transistor burns?
If inceres the base voltage of transistor them it may be burn . The base volt may be 0.8v to 1.8 If it use as a amplifier
How do you use the Transistor output terminals of an electronic counter in a Electrical control circuit?
They use transistor as the purpose to transfer the voltage
Why bypass capacitor of the second stage to disconnect to get the output?
we can use the Out Put Capacitor Ex Kvar
What is effect on amplitude shift keying modulation and demodulation due to use of transistor SL100?
The SL100 is a PNP medium power transistor, suitable for use up to ~100MHz. This can be used in the power amplifier stage, with the output connected to a tuning network/transformer + antenna for AM modulation. It's purpose, if used in this application, is to supply current (usually a voltage amplifier circuit will precede this one) to drive the antenna.
