DC Biasing, Load Line & Operating Point of Transistors

[@nagalakshmi6419]

Many have knowledge, but only few can explain in simple words . Ur lectures are interesting and easily understandable.👏👏

[@lavindisenarathne9499]

Exactly

[@adityakishore551]

00:09 Biasing is the process of applying external DC voltages to select the appropriate operating point of a transistor. 02:23 NPN transistor amplifies weak input signal without distortion 04:36 The input characteristics of a common emitter transistor involve the base current and voltage 07:08 The load line helps to find the input and output operating points of a circuit. 09:23 The output operating point of a common emitter transistor can be found by drawing a load line using KVL in the output loop. 11:46 The operating point of a transistor can be shifted by changing the base current or the resistance RC. 14:01 Operating point must be selected in the center of the active region to prevent distortion. 16:04 Operating point should not shift due to change in collector current.

SIR Just now i watched yr video on DC BIASING, LOAD LINE AND OPERATING POINT OF TRANSISTORS. Yr above video is inspiring. As i have come across in my experience, even many a B.E/ME graduates are unable to understand them properly, how nicely and convincingly u explain so well with such a ease and clarity that too with out the least confusion is amazing. You earned my highest respect, appreciation as well as my envy of your sound knowledge. while i have now understood many an important explanation u explained there still i have to grasp some few points being a slow learner. So i have recorded in my mobile and need to go thro them repeatedly. Yr video is outstanding. How i wish the speaking volume a little louder. Thanking you vatsa Bangalore India

[@lavanya9850]

Excellent explanation sir

[@grahamm5982]

Ive have for a long time now considered the possibility of utilising methods not known to current science.. I started to think outside the box and one of the first questions to arise was, does information have a physical weight? I.E if a hard drive has a maximum amount of data stored on it, does it weigh more then it did without data stored to the device.. The answer is no because machines operate using transistor switches to sequence binary code and gate positions are either opened or closed therefore no physical weight is added. This was a very significant question in that position sequencing determined overall machine performance and the fact that a program could actually be written to carry out virtual switch sequencing via software without it physically closing switches on the intergrated circuit led me to believe that I had just solved the issue of heat displacement in silicon based processors. If the transistors are all opened and utilised by the software they generate no heat from being open and closed but instead the software progam recreates binary gate functions via cloud computation and a virtual engine opens and closes the gates. My Hope is that someone takes this and changes the world. GM.

How to draw the output wave form

[@sowmyaamanchi5183]

tq man for clarifying doubts

[@venkateshanantapalli4343]

Sir at 14:53 minutes you explained the importance selecting the operation point. But you said clipping in terms of voltage for a positive half cycle(when Q1 is selected) while the clipping in terms of current for a negative half cycle(when Q2 is selected). Can you explain both the things in same point of view i.e., either voltage or current? Because if the current is zero means it doesn't mean the voltage is zero. And I also want to know whether the waveform you have plotted is current or voltage waveform. If you have plotted both as different waveforms means you could explain the thing in terms of power.

[@AnoNymous-po5sx]

Both waveforms are output voltage waveforms, but he explained Q2 load line with respect to current because it is where the active region ends. And if you go beyond that voltage, the saturation region begins. I figured this out so far, I'd appreciate to share your thoughts. :)

[@devkuanr13]

Thank you sir 🙏

[@manishthapliyal5886]

Sir, in output characteristics you said that by increasing base current ( IB) we can increase collector current(Ic) and this also serves the purpose of current amplification for which CE Config is made for. But sir my ques is that ideally base current should be zero because larger base current means larger recombination taking place which is not supposed to be the case. So why are we increasing Base current here to get more amplification.Please clarify these two contradictions.

[@amlanmaharana4882]

i think clearly sir has told that base current has effect on Q value while Q value has no such relation with collector current

excuse me sir i have a doubt... 8:14 you said if we increase 'Vce' curve will shift toward right. How exactly can we vary Vce?? isnt that the amplifed/output voltage? i mean how can we vary it? what is the process of varying 'Vce' Kindly answer it sir :)
