[@pranavsprobe7545]

There are so many physics teachers on youtube but no one is not having clarity in concept like you ! Hats off to u sir for your dedication:)

I am an Engineering student and love the way you explain tough concepts easily. I could not understand it in my classes and now with the help of yours it has became so easy. Love your videos very much sir. Please continue the good work.

Transistor as an *Oscillator* plzz Hit like 😎

[@mayankvatsa3710]

i think damped oscilator

[@smritisofia7691]

@Fernando Yael and u know what dude.. i saw the very same comment in some other video and somehow same reply by somebody who's either your friend or better say your other id, saying that it works... And someone had pointed this out there too.. so just stop doing this foolish act.. noone cares ..not even about your lies.. now FO!!

[@BrahmaSwaroopk_]

@Fernando Yael it's a scam

[@darshi2182]

From u r teaching i got 98/100 in an lab experimental test thank you❤️

Bahut bahut dhanyawad sir, 2002 me instrumentation engineering me kabhi samajh nahi aaya, lekin aaj aap ki videos dekh kar bahut kuch aasani se samjh aa gaya

[@harishankarkarthik3570]

One of the best videos I have ever seen

Literally..u have a great knowledge of the topic..

[@user00774]

kaur ?

[@lalitalalita2596]

sir amazing lecture ncert ke topic jo grasp nahi kar sakte wo ab crystal clear ho gaya hain thank u so much sir

[@mr._shri_0837]

I have done my diploma in electrical engineering in 2020. But I did not clear my basic electronics doubt when I saw your classes everything clear . Thank u so much sir . I got clarity in my doubts.

[@banarasi_babu_0820]

No problem Sir.

[@SanjayKumar-ng9id]

Sir, Seriously aap critical bate bhi badi asani se samjhate h Really you are a great teacher Please introduce load line & q point also

Case 1: Vi < 0.7 V When the input voltage (Vi) is less than the threshold voltage of 0.7 V, the base-emitter junction is reverse-biased, and the transistor is essentially turned off. In this case, both Ib and Ic are approximately zero, and the transistor acts like an open switch. The voltage drop across the collector-emitter junction (Vce) is equal to the supply voltage (Vcc). Now, suppose we gradually increase Vi. As Vi increases, the base-emitter junction becomes increasingly forward-biased, and the transistor begins to turn on. The base current (Ib) starts to flow, which in turn causes the collector current (Ic) to flow. As Ic increases, the voltage drop across the collector-emitter junction (Vce) decreases, according to the formula Vce = Vcc - Ic*Rc. Eventually, at some Vi value above 0.7 V, the transistor enters the active region, where it is able to amplify the input signal. In this region, the collector current is proportional to the base current, and the voltage drop across the collector-emitter junction is much smaller than Vcc. Case 2: Vi > 0.7 V When the input voltage (Vi) is greater than the threshold voltage of 0.7 V, the base-emitter junction is forward-biased, and the transistor is turned on. In this case, both Ib and Ic are nonzero, and the transistor acts like a current amplifier. The voltage drop across the collector-emitter junction (Vce) is given by the formula Vce = Vcc - Ic*Rc. Now, suppose we gradually decrease Vi. As Vi decreases, the base-emitter junction becomes less forward-biased, and the transistor starts to turn off. The base current (Ib) decreases, which in turn causes the collector current (Ic) to decrease. As Ic decreases, the voltage drop across the collector-emitter junction (Vce) increases, according to the formula Vce = Vcc - Ic*Rc. Eventually, at some Vi value below 0.7 V, the transistor enters the cutoff region, where both Ib and Ic are negligible. In this region, the voltage drop across the collector-emitter junction is equal to Vcc, and the transistor acts like an open switch.

[@utsavneogi2751]

Sir, this is out of syllabus for us in this year. Still I am learning from you because your lectures are awesome.

[@pi_rand4266]

Best video on transistor as a switch

[@syedsajidiqbal7157]

So helpful Sir....

[@PoonamSharma-dp3sr]

What an explanation so nice.... U made me understand the whole concept... God bless u🙏🙏🙏🙏

[@tapasyatembhurney5007]

Thankyou so much uh explained it in the best way !!!

[@rishikeshdash007]

Thank you so much sir.. i see many videos on this topic.. but you are the one that diffentiated between the input voltage and the barrier potential.. most of rhe time many take Vbe as the input potential.. Making so much confusion.. hatts off to sir..👍👍👍

[@zahirullah19m48]

This explaination realy helped...thank you sir

[@rohankaurav1780]

Nice explanation

[@tufailyarlook3620]

Highly informative sir.thanks🥀💙.

[@chhavichetiwal5266]

Sir your explanation is very good Sir transistor as a current source par bhi lecture banao

[@sabrinaaktertrisha2909]

Thank you sir ❤️

[@IronMan-fe8kv]

sir, we take v input Vbb and then we take Vbb as .7v but for breaking the barrier potential we want Vbe as .7v not Vbb 🧐i.e the potential across the junction should be equal to the barrier potential.

[@addictionforphysics8509]

But sir not take VBB as 0.7 V VBB is always greater than VBE(voltage drop)

[@menezesgamacrizellegracefy8665]

amazingly explained

[@sharvilpatil60]

sir pls make video on power amplifiers

[@Akash-k007]

Exam ke pehle dekha ye video, bacha liya sir aapne.

[@baltistaniacademytech7912]

sir, you are great, and your writing is clear. Please tell me which software is that?

[@dhananjoyghanty4546]

You are greate sir

[@zayn2692]

Gr8 explanation

[@JEAjayKumar-so5by]

nice this helps me to understand well

[@shubhangikumari4204]

Thank you for such clear explanation

[@Dukh_Nirodh_pratipad_Gaamini]

Rc resistor Wala part to reverse bias me h to usme se current kaise flow hoga jab transistor ka potential >0.7V hoga to Plz answer

[@shubhangikumari4204]

Reverse bias ka breakdown voltage hi 0.7V hai , jab input usse zyada ho ga toh current flow karne lagega

[@adityamahilane5709]

Gajab sir

[@KhushiGupta-nq7en]

10 on 10....thank you sir

[@modernphysics7474]

Superb explanation 👏👏👏

[@laharbhagvat991]

1000% good 🌹

[@cricketlover8649]

So what difference in diode and transistor? Means we can use transistor as switch also?

[@tr4661]

very helpful.. thankyew sir🙏

[@nitya703]

Sir, please make a video on transistor as an amplifier.
