This is the best Thevenin's theorem + example video I've seen so far (I've watched half a dozen by now). Thank you for the clear and concise video! Bless you
I’ve been studying all day and this is by far the most helpful video I’ve come across thank you so much!!! For anyone who needs a step by step explanation this is for you
Thanks for this. The book I’ve been using to teach myself wasn’t very good at explaining things and I needed the guidance. Now I understand why this theorem is so important.
Best explain,I will give out of out 100, Becouse next Tommrow of my exam in college in BTech in electrical engineering in 3rd sem. But I understand concept only in one time' but my professor was explained all time😅😅😅
Thank you for short and understandable lesson videos . Can you make videos about Biomedical İnstrumentation , bioMems , signal processing and biomedical devices , like other videos ?
Do u think potential difference is the only reason why current flows ? V=IR( ohms law ) Here resistance is zero that's why no potential difference or no potential drop but current ain't zero right ? It's the resistance which is zero
Yes it is , in the starting you can see that it's already mentioned that Rth is input/equivalent resistance at the terminal... So I think that we calculate it like that only
For voltage sources, we set their voltage to zero, effectively replacing them with a short circuit. For current sources, we set their voltages to zero, effectively replacing them with an open circuit.
The answer should have been 24 V had the two resistors been in series. They are in not in series or parallel so the voltage Or current division rule cannot applied. Note that there is a current source of 2A connected between them making the point a principal node.
@@hemantbhatt3553 can’t we use a simple mesh analysis equation -32 + 4i +12i =0 I=2A and the same current flows through entire circuit. As the 1ohm resistor is open and voltage can’t flow. The resistance at 12ohm is v=ir 12x2=24volts and since 4&12 ohms are series same voltage flows and Vth is 24volts
I did'nt understand the voltage source removing to find the equivalent resistance . One is short circuited and otherone is disconnected . Please if u can recommend me a lecture to understand it. Thankyou for the lecture.
As explained in the lecture, we replace the independent source by its "internal resistance". An ideal voltage source has zero internal resistance and hence we replace it by a short circuit, and an ideal current source has infinite internal resistance and therefore we replace it by an open circuit.
Thank you soo much sir for explaining these concepts in easiest form . I'm very helpful from your videos . Plz provide PDF 9f these lectures will helps me alot for digital learning although I already made notes but also want pdf plz sir 😀🙏❤️
if Vx = Vth shouldn't the -2A current be not there since current flows from high potentilal to low. the current shouldn't flow since Vx = Vth. am i wrong?
I have the confusion when I solve the circuits problems ...let assume 3 resistors are in parallel and 2 resistors are in parallel suppose we solve 3 resistors which are aeries their equivalent will be ? With 2 parallel resistors I can't understand the logic

What if there was a dependent source in between then we have to do nothing with it na sir?

A doubt; How the $ ohm resistor and 12 ohm resistor are parallel and those are in series with 1 ohm resistor?
@@gamerclash7092 because same current will not flow accross 4 and 12 ohm resistor so it will be parallel.
thanks teacher.... I have been trying to understand this topic for 3 hours and it lasted 13 mins thanks for your video
1 night before exam 🗿
No change....again excellent teaching....love towards NESO 😊😊
Didi Can you please help me in understanding that why did he short circuited the voltage source but open circuit the current source ?????
Plzzz

tbh i tried understanding Thevenin's Theorem in book it is very complicated and messy
you explained it very well
never knew it was that easy
Thank you sm, I understand clearly now.
nice video, just a question, why Rth is not 4?
Thank you..... I understand perfectly.....☺☺☺
please also make a video of Norton's theorem
Do we only apply the vx where there is a voltage drop?
thanks for explaning it , it really helps .
Wonderful explanation.
Thank you sir but having one doubt from where you get 4ohms??
very helpful. Thank you!!
Thanku sir
Simplicity exist here.
You guys are doing a good job keep it up well done
Thank you very much for this.
Sir you are the bast teacher
Why 12 and 1 ohm resistor are not parallel with series on 4
i.e (12||1)+4 ...why ,please help......
Sir Vx=Vth, why i3 current between Vx and Vth , there is no potential difference......?
i know right
Do u think potential difference is the only reason why current flows ?
V=IR( ohms law )
Here resistance is zero that's why no potential difference or no potential drop but current ain't zero right ? It's the resistance which is zero
🆕 @Nini 🆕 Sanjay 🆕 New 🆕🆕
Since VX=vth, so potential difference is 0 here.
9:42 I don't understand the looked from part , how we looked from there ? Isn't that general Req ?
Yes it is , in the starting you can see that it's already mentioned that Rth is input/equivalent resistance at the terminal...
So I think that we calculate it like that only
I'm watching just 15 minutes before exam😉
Thanks for this ice informative lecture.
Awesome video about Thevenin's theorem! I needed this and this is perfect for me
its not 3vx-96 it is 4vx-128+vx
Thank you Sir!
While calculating Rth why voltage source considered as short circuit and current source as open circuit??
For voltage sources, we set their voltage to zero, effectively replacing them with a short circuit.
For current sources, we set their voltages to zero, effectively replacing them with an open circuit.
Watching this 15 minutes before exam
great writing mate
sir why have we considered 1 ohm for calculating equivalent resistance but not for calculating voltage
Why we can't apply voltage divider for Vth
Vth=32*12/(4+12)= 24 Volt
While in soln Vth= 30 Volt
I have same doubt
The answer should have been 24 V had the two resistors been in series. They are in not in series or parallel so the voltage Or current division rule cannot applied. Note that there is a current source of 2A connected between them making the point a principal node.

8:03 3vx-96+vx=12 right? Not 24
Am I right.
No. You are doing some calculation error. When taking the LCM, which is 12, the -2 will be multiplied by 12 to give -24.
