Sir at 9.25 when input resistance becomes infinity, by substituting the value of input resistance value in overall current gain eqn then it becomes infinity only how it equals to current gain
'Is' is just the input supply, unless you are using superconductors(i.e materials which offer zero resistance to electron flow) for the connections and the construction of the source itself; there will always be some kind of source resistance, which we consider as 'Rs'
@@girishkumarpeddi6266 Even if Rs is not zero, the current going through it is the current coming out of Vs and the same one circulating in the input loop labeled "i1". Since the current out of Vs it's being called "is", then "is" = "i1". Now, if instead of a Vs with a series Rs, the input was a current source Is with a large parallel resistance Rp, I would agree with all the calculations done at 8:20. But, as the problem it is stated, I see no need for it, and like I said before I belive that "is" should be equal to "i1" straight away.
My most favorite and lovable invisible lecturer with a pleasant voice.thank u for all ur beautiful lectures. Thank you NESO
I love all the lectures with simple calculation made by Neso academy..
in the last section in the matrix i i1 should come up and v2 should go down
Exactly
exactly yrr
shoud the matrix at 10:45 have i1 at top instead of v2
Akhil Garg yes
yes
U r awesome sir this is one of the best channel for study
Nice.explanations
Shared to all my classmates
Sir please make more videos on feedback amplifiers at a deep concept
I liked the last explanation of Δh what you have drawn from determinant derivation..
matrix method is just too good.Thanks.
Sir , u didn't derive the expression for input impedance...
I am loving ur work tho :) appreciable❤️
Thank you very much sir, your videos are always useful and helpful
Thanks for good explanation.
Simplified, thank you very much sir
awsssome sir.
ur videos helped me so much....
plz keep it up sir with best
Sir op!!
Can you make the video on small signal analysis on fet transistor and what difference b/w bjt s.s.analysis and fet s.s.analysis
Plz upload power amplifier lectures also...
Thank you sir
Why is Rs infinite for ideal voltage source? If it is then the current through ideal voltage source should be zero?
chaa modiye bhai sahab
Love you sir❤️
Thank you very much for this!
thank you your videos is really good
Can you please make a vedio on calculating voltage and current gain of ce amplifier with numerical values
Nice sir
Where is the i/p admitance & o/p admitance? Would mind please these topics also...
Thank you
Why ideal voltage source Rs is 0 & ideal current source Rs is infinite
Samik Das In case of ideal voltage source, there is no internal resistance. That's why......
Thank you very much
Sir at 9.25 when input resistance becomes infinity, by substituting the value of input resistance value in overall current gain eqn then it becomes infinity only how it equals to current gain
If rs becomes infinitely then the current passing through it will be 0 so is=i1 therefore i1/is =1
Take out Rs as common from denominator and then substitute Rs=infinity.
Why ho connected in parallel in output ckt???
thank u but i would prefer the lecture to be a little bit slower....
Noooo
no
of course not...... !!!!!!
you kidding? I am going through the whole series at 2xs speed. wishing i could make it 3xs lol to each their own pace
Watch it at 0.25x
Why the norton equivalent of Vs? Why isn't "is" = "i1" straight away?

the matrix I should have v2 up and i1 down
Why I1 and Is not same. I1 is from the voltage source same as Is without change the circuit to equivalent current source
Shouldn't Ais=Ai*Rs/Rs+Zo instead of Zi?
It would be easier if u were to have an example
🙏🙏
I want analysis of Rc coupled amplifier using hybrid parameters
