I assume a series of amplifiers with one F/B The F/B is the portion of voltage/current F/B from input to output no matter how many amplifiers are in series within the loop or what the gain of each one is.

∙ 13y agoThe 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).

the i/p and o/p resistances of current-series feed back get to increase due to the series connection at input and output

Input impedance of current shunt feedback amplifier?
The input impedance of a current shunt feedback amplifier is the open loop impedance of the amplifier divided by 1+(A*beta)
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.
Explain current shunt negative feedback amplifier?
describe current-shunt negative feedback as applied to operational amplifiers, including derivations of the gain relation for each type of negative feedback.
What is the difference between an amplifier and a booster?
an amplifier is electronic equipment that increases strength of a signal and a booster is voltage regulation in (DC) direct current electrical power circuits. Basically an amplifier increases strength and a booster regulates voltage.
What is produced first current or voltage?
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Types of Negative feedback amplifier?
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback

What is the sampler and mixer in current series feedback amplifier?
Here it is the current sampler and it is connected in series. while the voltage mixer connected in series.

What is the difference between normal amplifier and operational amplifier?
To oversimplify it the "operational amplifier" was originally designed to perform mathematical operations in electronic analog computers. The designer set the mathematical operation of each amplifier by designing its feedback network. Some operations that could be done were: addition, subtraction, constant multiplication/division, logarithm, exponentiation, variable multiplication/division by combining logarithm-addition/subtraction-exponentiation, integration, differentiation, absolute value, clipping, etc.A "normal" amplifier was just designed to produce a certain amount of voltage or current gain.
Which element acts as feedbacking element in current series feedback amplifier?
A: It not an element but rather a components like a resistor or capacitor and/or a combinations of both.
Why ce configuration of transistor has a 180 phrase difference in output?
A: As current begins to flow the action on a resistance will be a voltage drop which is inversely proportional to the current. Making it a voltage amplifier as opposed to a tube where it is a current amplifier
