Bandwidth does not change with frequency. Bandwidth defines (part of) how the response of a circuit changes with frequency. Other things that define how the response of a circuit changes with frequency are: phase shift, roll-off rate, linearity of the passband, etc. but bandwidth ignores these.

What is the theory of voltage series feedback amplifier?
In a Voltage Shunt feedback Amplifier, the feedback signal voltage is given to base of transistor in shunt through a feedback resistor.This Shunt connection decreases the input input impedance and voltage feedback decreases the output impedance. In this amplifier input is current and output is voltage. Thus Transresistance is stabilized.Input and Output impedances are reduced by a factor of 'D'(desensitivity factor). Advantages: 1)Gain independent of device parameters. 2)Bandwidth increases. 3)Noise and non-Linear distortion decrease. 4)Prevents Loading effect. 5)Acts as good source for the next stage.
Explain current shunt negative feedback amplifier?

Difference between amplifier and feedback amplifier?
An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.

What is the difference between voltage series and current series amplifier?
The main Difference between Voltage and Current Feedback Amplifiers is in the sampled(Output) signals. In Voltage feedback the sampled signal is voltage (Vf=Beta*Vo) where Vo is the sampled signal and for current feedback it is current signal (Vf=Beta*Io).
