Sir plese contact number kuch baat karna hai plese sir
Pen change Kariye sir

Watch the two videos below which discuss these aspects beginning with descriptions of differential-mode and common-mode currents with animations. A basic scheme of a differential amplifier is introduced with the description of the analogous operation of a U-tube manometer. This is followed with a description of enhancements to the basic scheme of the amplifier to make it suppress common-mode output voltages more efficiently.
The Basic action of a Differential Amplifier- the heart of the Opamp.

Differential-mode and common-mode signals are important to understand in the design of complex signal-conditioning circuits which use operational amplifiers in medical diagnostic, industrial control and military applications.
Engineers are so used to thinking and visualising currents as differential-mode in circuit analysis that they find it hard to switch their thinking to common-mode currents and their effects in say, amplifying circuits.
It will be instructive to understand and visualise Current at its most fundamental level in the presence of electric fields in ordinary conductors.
Electrostatics and circuits belong to one science not two. To learn the operation of circuits, Current and the conduction process, resistors and how discussing these topics makes it easier to understand the operation of capacitors, inductors, diodes and their operation in amplifier circuits and circuit theory watch these two videos

Most common-mode signals originate because of sources external to the system, and the energy in them circulates annoyingly until it is dissipated in resistive portions.
Therefore the need arises for amplifiers to amplify only the useful differential signal and reject the common-mode component which does not belong to the signal conditioning system. Such an amplifier is used as the first stage of an operational smplifier which opens the door to allow a signal from a sensor ‘in’, so to say and so the importance given to this stage.
Operational amplifiers mainly excel in performance to provide a high common-mode rejection ratio and high gain. By using negative feedback, its overall gain, input imledance and bandwidth are determined by external components without these parameters being affected by the op-amp’s parameter variations due to external influences like temperature and so on.
Most amplifiers built using discrete transistors will not be able to match the performance characteristics of an operational amplifier like CMRR, low drift, high input impedance and stability of gain.

Most common-mode signals originate because of sources external to the system, and the energy in them circulates annoyingly until it is dissipated in resistive portions. They can be generated internally if proper cables are not used for coupling signals at the frequencies of the signals they carry.
Therefore the need arises for amplifiers to amplify only the useful differential signal and reject the common-mode component which does not belong to the signal conditioning system. Such an amplifier is used as the first stage of an operational amplifier which opens the door to allow a signal from a sensor ‘in’, so to say and so the importance given to this stage.
Topics related to these aspects are discussed in chapters 3 and 5 of textbook 4 (see last frame References in video #1) and a power point presentation with animations “Basic Action of a Differential Amplifer-Heart of the Opamp” which explains differential amplifier with a U-tube manometer analogy of differential- and common- mode signals is included in the CD alongwith this book.
Also in textbook 4 you will find descriptions using a unified approach towards an intuitive understanding of "circuit zero", "neutral", "ground" and "earth".
Thanks sir
Sir please update it, I mean please give a link for the next video in the description or a pinned comment as well as the link for the full playlist of this particular course. Please sir
Nice
yaaaaaaaar, clg ka 2 ghante ka lacture se ish 10 min ka vdo kitna badiya hai bhaaiiii...........
Dozzed and slept after listening this video 😴😴
Brightness jyada h sir ji but you provide us good better and best explanation 🥰🥰🥰🥰🤘🤘🤘🤘🤘💪💪💪
Do you have solutions of this book sir I couldn't find it anywhere

Sir defination Bhi likha kijeye to aur achha sai samjh m aya hain
What is A?
really helped 1 day before exams
Thanks
Same video in Hindi sir please
wHAT TYPE OF IC U USED
If only I can turn back in time back when I was a student in my cursed university I could have a much perfect grade but sadly I couldn't succeed because I got passed grades and I couldn't even continue for the postgraduate. 😢😢
I love electronics trying to learn it alone. Ive been throw 4 videos of famous to get how opamp works damn i didnt get a word then im blessed with this video and tada its so simple
Could anyone please answer these..
1.What does number 7431 represent in IC7431?
2.Why do we have different IC's for different logic gates?
What is Vd??????
It's amazing 😍
Thank you sir 🙏
Nice teacher!!
go ahead beta...
Great video sir! Thank you!
Fantastic, sir, please cover the other physics also, in a complete form
sir if possible can u provide all the pdfs
aj meetha meetha he
Humare sir ko bhi kuch sikha de😂
