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.

∙ 11y agoApplication of voltage series feedback amplifier is that it can be used as a source follower (which is called as the drain characteristics) and emitter follower (where the input impedance is high whereas the output impedance is low which is good for frequency response) from which the feedback gain, input resistance and output resistance is determined.

Isolating transformer theory?
Transformers use magnetic induction between 2 coils of wire to produce a voltage in the secondary winding. Typically the main purpose of a transformer is to step up or down the voltage by having differing number of windings between the primary and secondary coils. A secondary effect is to keep the 2 systems electrically isolated from eachother. If one of the phases becomes grounded, the ground is only seen on the portion of the system downstream of the transformer, thus increasing relibability.
Why do we study theory computation?
a computer is what?? it is simply a machine made of hardware??but why we need computer....the answer is we need computer to perform computation on a specific task....how this computation will occur in the computer is defined by a set of rules ...to understand these rules ,we need to study theory of computation.... theory drives practice and practice drives theory....to make efficient machines for computation tasks we need to study theory of computation.
Which theory compares light movement to dropping a pebble into a pond?
The theory of comparing light movement to dropping a pebble into a pond is called light refraction.
What is quarts theory?
Actually it is spelled with a "z"...quartz theory. I think you may be referring to Quartz Crystal theory. When the metals described on the periodic table of the elements come into contact with each other or are changed by chemical reactions in a lab, their properties can be drastically altered. The crystal theory explains why these property changes occur and helps scientists predict exactly which changes will happen.
What 3 things does an electrical amplifier amplify?
An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.

In a series RLC circuit at frequencies above resonance is the circuit capacitive or inductive?
in series you XL, voltage leads the current, and in Parallel current leads the voltage. so your answer should reflect on this theory.
Theory of RC coupled Amplifier?
In a two stage RC coupled amlifier the rransistor are identical and a common power supply is used. the output is provided to the first stage of the amplifier wher it is amplified and this output is uses as a input for the sexound stage this is amplified once again by the other transistor in the sexound stage and the final out put is obtain.

What will be the output voltage if reference voltage is short circuited in a series voltage regulator?
In theory it will be zero, in real life it's 0,003-0,005volts. Because the rule of ohm says: U = I * R. Shorted means that R = (almost) 0 so U will be close to zero too.
