Maximum Power Transfer Theorem Using Nodal Analysis & Thevenin Equivalent Circuits
HTML-код
- Опубликовано: 26 июл 2024
- This electronics video tutorial provides a basic introduction into the maximum power transfer theorem which states that the max power delivered from the source to the external circuit occurs when the load resistance is equal to the thevenin resistance. This video explains how to use the thevenin equivalent circuit and nodal analysis to calculate the thevenin voltage & resistance as well as the maximum power delivered.

This man teaches me more than my professor does, thank you sir! (2)
Ur professors goal is to introduce you to the lecture, I don’t think they’re trying to make you get it, if you get it you get it, if you don’t review it. Sadly
@@BiggMOE-jv5jltrue. people think you go to school to learn, you go there to get introduced to topics
I have a biomedical electric circuit exam, I did take 8 lessons this semester and 4 weeks till midterm passed like racing.. I am really grateful to you that you taught me everything in 2 days. From current bla bla to loops nodes, nodal analys, mesh current problems, max power thevenin.. Dude you are freaking superman of teachers. Not electric, definitely you are good at teaching. Thanks a lot.. No matter passing the exam.

You have my eternal gratitude. I literally watched this when I have less than an hour left before my quiz.
Very well explained. Really thankful to you for this video.
Thank you for your service to humanity.
Damn, who is also watching this one day before the exams?😂😂
☝️
You are not alone 😅
That’s bad habit 😊😊😊😊
the hour before exams🥲
Exam is in 30 minutes 😢
Finally im looking for this thanks Prof.
2 years and still useful, like bro loved the video 🙇🏻♂️
Another great video; you explained with this video somewhat better the utility of the Thevenin Voltage and Thevenin Resistance. Also, I liked how you showed which current source would be dominant by examining voltage drops through the different resistors!
Love you bro, truly a master at your craft its inspiring to see
thank you so much, really appreciate your tutorials
Excellent explanation.thank you so much.keep it up❤
You have a video for everything, WOW! Thank you sir !
I've been waiting for this last year. 🙃 now finally it happens
I love this man
Nice lecture keep it up
Thank you so much!
Thank you very very much.
thanks for the great video
hey for real... i am studying mechanical engineering and if i see you have a vid on one of my subjects i feel so much relive keep up the good work :) afther i grad will make a donation if you have a paypal or paytrion :)
did you grad
he died last year in a motorcycle accident

Thevenin equivalent resistance Rm (in ohms) at terminals (a, b) is Ph a b. 0 R1 9% If v, 2 v, R1 4 ohms, and R2 10 ohms, the current li (in amperes) is b. 0 c. 1.5 d. 3 e. 10 R1 If Vs = 9 V and R = 10 ohms
how th youmade these become so easy? tysm
Thanks from Somalia
I have an unrelated question please. I wanna review Organic chemistry but I found 2 playlists. I don't know which one I should pick. What is the difference between the new and the old playlist?
Thanks a lot!
GREAT. job know I understand how Thevenin theorem works.
Great.. Thanks :)
good video
thanks prof.
Thank you sir.
thank youuuu
At 4:08, why can we use the voltage-divider theorem while the two resistors are parallel?
Thank You
Please cover all the science topics
Sir can u do a full overview on thermodynamics please . I have many doubts in it
Balamurugan P plz
😁😁😁😁you are just awesome 😁😁😁.... Nothing to say
could you show examples with dependent sources pls
it looks simple
thank you pretty much!
uff at last, i have found my medicine for the exam tomorrow🤧🤧
THIS NIGGA ALWAYS SAVES ME IN MY FINALS
life saver
Hey sir how do you find the percentage of the power supplied the voltage source
is it possible for this circuit to be solved with consecutively Thevenin theorem to find the Vthev and not Kirchhoff?
at 6:45 why did we remove current source? , like we are ignoring the voltage supply and short circuiting the circuit , but why not do the same for current source?
If power =V*I , indicates which values of V & I are the maximum power point
Now I know thevenin !
For the first example whats the methos called when u basically combined the 17R and 24R to have a simpler circuit to solve for Vth
At 12:28, why not transpose -48 to the right side of the expression?
Why do you multiply by a quarter when you calculate the power from where it comes from?
I love you !!
Bro but seriously how tf do you have all these knowledge
Regarding at the 2:00 timestamp, shouldn't the 17 ohm resistor cancel out? Since terminals A and B are open.
That's what I thought
You are calculating the net resistance between point A and B so , u can see how current can move from B to A and the mentioned current cannot reach point A without going through 17 ohm resistor
thank you so much but please try to make "t" better ... it look like V(t+h).
but love you !!!!!! 🥰
In 7:06 why did he took the 7 ohm resistor? I thought it’ll be zero cause it’s an open circuit?
Pls correct my information
not zero
He is not talking about current , current would be zero
Resistance would not.
Genius
is there a deeper explanation video for these equations?
Watching On exam day
10:13 Why the amperage in the 4 Ω resistor is Ι=5 Α. I get that the amperage source is givinge 5 A, but doesn't the voltage source influence the current?
No because two things, there is no current flowing through the 7 ohm so there must be 5 amps flowing thru the 4 ohm, since 5 amps enters that node. And it doesn't matter what the voltage source does, the current source will adjust it's voltage so that there is 5A always flowing thru it's branch. Which includes the 4 ohm in this case too as there isn't even a node between the 5A source and the 4 ohm because, the 7 ohm isn't connected to anything rn.
What do u mean by PL/RL
WHY IS THE 12 OHM RESISTOR IS IN PARALLEL WITH THE 24 OHM RESISTOR RATHER THAN IN SERIES
❤️
why was there no current flowing through the 17 ohm resistor
I don't get it:
1. how is it possible that the current passing through the 6 ohm resistor is not twice as big as the current passing through the 12 ohms resistor since the voltage and current are the same in point D?
2. how can you have a bigger voltage inside your circuit compared to what the source can provide?
I don't quite understand it myself either though I used an app for macOS called iCircuit to create the circuit and his results are correct. I wonder if an analogy would be to a river that receives tributaries and at certain points along the river the contributing flow of water creates separate sections or pools where there would be more water present at some particular points than at others?That's my guess ‼🤕😵💫🤯🤷
At 14:25, I used the source transformation method and I arrived at 36V for Vth not 56V.
I actually used source transformation and was able to get 56V
I also obtained Vth as 56V
Why need to change the resistance from 1/6 same as 2/12? Why must change it?
Just to simplify the calculations since he's not using a calculator. You can use it directly no problem
source transformation
Tell me please::
device name you writing 📝📝📝✍✍✍🙏
Lakshan Chamod did he tell you in person
what do u mean PL
/RL=0
There was a mistake in Pmax expression. Here is the correct one Pmax = 1/8 (Vth^2)/Rth
He is crt
woah i’m kinda early
Couldn’t you just use source transformation to simplify this. Seems rather tedious using pure nodal analysis
Ok
First
On 6:58, he says that the 6ohm is parallel with the 12 ohm. How come the 6 ohm and 12 ohm aren’t in series but are parallel?
For two resistors to be in series, it needs to be on the same branch carrying the same current. The 6-ohm and 12-ohm resistors are not on the same branch. If you simply pull the 6-ohm resistor and place it on the left-most vertical branch, it is easier to notice that it is parallel to the 12-ohm resistor.
is there anything that you can't teach. 🤯🤯
Comment
JEE EXAM 😆
you beautiful bastard
Your work in electronics is a mile wide and an inch deep. I hope actual EE students aren’t miss lead by a high school level treatment. They will fail.
I am an EE student in college and these videos have been saving me, although I am only in the first class in my Universities EE line.
Thing is i think sometimes this guy is just bs. Not gonna lie I have studied his shit for a while and they may help at times. but mostly it's just he uses these formulas that don't ake any sense. Like this scenario where Pmax=1/4*vth^2/rth. We know that Pmax is when the rth=rl so p=vth^2/rth...what does the 1/4 do here? In another unrelated topic under probability, when using z table to get confidence levels, he used a simple technique to get AL when that isn't even the way to do it. You just made me look like an idiot trying to explain to my professor how I got my answer.
You are dead wrong, 1/4 is needed.
Your the best 🫂🫂🫂🫂
