The current series feedback is a negative feedback in which the output current feeds back a proportional voltage back to the input terminals in series with the input signal.
Here the output impedance as well as the input impedance increases as both are connected in series.

How do you identify a particular feedback topology in a circuit?
For analyzing the feedback amplifier, it is necessary to go through the following steps. Step 1 : Identify topology ( Type of feedback) 1. To find the type of sampling network (i) By opening the output if feedback signal becomes zero, then it is called "voltages sampling" (ii) By shorting the output loop if feedback signal becomes zero, Then it is called "Current Sampling" 2. To find the type of mixing network (i) If the feedback signal is subtracted from the externally applied signal as a voltage in the input loop, it is called "Series Mixing" (ii) If the feedback signal is subtracted from the externally applied signal as a current in the input loop, it is called "Shunt Mixing" Thus by finding the type of sampling network and mixing network, type of feedback amplifier can be determined. for example, If amplifier users a voltages sampling and series mixing, then it is called a voltages series 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 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).
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 feedback amplifier?
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.
