Voltage has nothing to do with it. THE LOAD LINE ON THE OTHER HAND HAS EVERYTHING TO DO WITH IT.
Yes. Two or more linear amplifiers can be connected in series. The impedances must matched between them, and also the undistorted output power available from from the first amplifier must not exceed the input power required by the second amplifier to deliver its maximum undistorted output power, and so on. An example arrangement might look like this: 1 watt transmitter -> 10 watt amplifier -> 100 watt amplifier -> 1000 watt amplifier Amplifiers can be connected in parallel under certain conditions. The amplifiers must be identical in gain, phase, and amplitude performance. They should be identical in all respects for best success. A combiner or hybrid circuit is used to split the incoming signal equally between the amplifiers, and a (larger) hybrid circuit is used to combine the outputs of the amplifiers into one comon signal. YOU MAY ADD another more powerfull amplifier on the output in series to the original amplifier. What you realy want is a parallel amplifier to doubble your power.
Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases
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.
In Voltage Shunt Amplifier, the Output voltage is supplied in parallel with the Input voltage through the feedback network.
output resistance decreases and input resistance increases
Yes. The "275W" is the maximum power that the speaker can handle at its input. The "120W" is the maximum undistorted power that the amp can deliver in the loud spots with the volume wide open. So the amplifier will never overdrive the speaker. The impedances of the speaker and amp-output should match. If one of them is marked "4 ohms", then they both should be. If they're not the same, then . . . -- the speaker may not sound as 'crisp' as it should. -- the amplifier may not deliver as much undistorted power as it should. -- the amplifier may not run as cool as it should. -- with an extreme mismatch and extended loud spots played at high volume, the amplifier may even be damaged.

as it is rate of change of output voltage..so it affect amplifier output
Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
The bandwidth of a circuit, amplifier etc has been chosen to be defined by the points when the power output falls to half its maximum. Log 0.5 is -0.3 which in the decibel notation is -3dB (-0.3 Bels= -3 decibels). When the output power is at 0.5 maximum, then since the power varies as the square of the voltage, the output voltage is 0.707 of the maximum output voltage.
Depends on the output of the amplifier.
An amplifier with tuned filters on both input and output.
The amplifier whose output is inphase with it input means if we consider voltage amplification then there is zero phase shift in input and output
Yes this amplifier is a mono amp so it is internally bridged. It does not have a stereo output.
Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases
