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
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.
whoa you could start a whole new series on nodal analysis with different methods and solve complex circuits , this video was so fun to watch , pls make more circuit analysis
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!
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 :)
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
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.
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
question here Vd is calculated at 36v and we know I1+ I2 = 5Amps, We know I1 = (Vd-24)/6 which makes I1=2amps which means I2=5-2=3Amps. why is there more current at I2 even though resistance is higher????
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!
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 ‼🤕😵💫🤯🤷
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.
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?
It may be a little late, but here is the reason. A voltage source turns into a short, because the internal resistance is 0, whereas a current source disappears because the internal resistance is infinite. I don't know exactly why, but that is just what it is.
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.

That’s bad habit 😊😊😊😊
the hour before exams🥲
Exam is in 30 minutes 😢
bro just tell me who tf are you. youre the creator of every video im looking for
I never understood my lecturer but this man has made me understand everything
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!
Our professor said at point C, potential is zero. But when I did node analysis it is not zero as you mentioned in video. Thank you!
2 years and still useful, like bro loved the video 🙇🏻♂️
Very well explained. Really thankful to you for this video.
Finally im looking for this thanks Prof.
I don't knw y anytime I watch ur video
I feel happy
U have charmed me 😂😂😂😂
You have a video for everything, WOW! Thank you sir !
I've been waiting for this last year. 🙃 now finally it happens

uff at last, i have found my medicine for the exam tomorrow🤧🤧
it looks simple
thanks for the great video
GREAT. job know I understand how Thevenin theorem works.
I love this man
this guy is my messiah
Thanks from Somalia
At 4:08, why can we use the voltage-divider theorem while the two resistors are parallel?
Nice lecture keep it up
how th youmade these become so easy? tysm
Thank you very very much.
Thank you sir.
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.
Thank You
😁😁😁😁you are just awesome 😁😁😁.... Nothing to say
Sir can u do a full overview on thermodynamics please . I have many doubts in it
Balamurugan P plz
is there a deeper explanation video for these equations?

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 !!!!!! 🥰
good video
could you show examples with dependent sources pls
Please cover all the science topics
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?
I love your voice
Why do you multiply by a quarter when you calculate the power from where it comes from?
Now I know thevenin !
Hey sir how do you find the percentage of the power supplied the voltage source
Can any I explain why current due to current source and voltage source is not being added in arm DC?
question here
Vd is calculated at 36v and we know I1+ I2 = 5Amps, We know I1 = (Vd-24)/6 which makes I1=2amps which means I2=5-2=3Amps. why is there more current at I2 even though resistance is higher????
is it possible for this circuit to be solved with consecutively Thevenin theorem to find the Vthev and not Kirchhoff?
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.
Genius
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
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!
If power =V*I , indicates which values of V & I are the maximum power point
thank youuuu
Great.. Thanks :)
Watching On exam day
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
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?

WHY IS THE 12 OHM RESISTOR IS IN PARALLEL WITH THE 24 OHM RESISTOR RATHER THAN IN SERIES
Bro but seriously how tf do you have all these knowledge
I love you !!
source transformation
What do u mean by PL/RL
why was there no current flowing through the 17 ohm resistor
Tell me please::
device name you writing 📝📝📝✍✍✍🙏
Lakshan Chamod did he tell you in person
There was a mistake in Pmax expression. Here is the correct one Pmax = 1/8 (Vth^2)/Rth
He is crt
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.
what do u mean PL
/RL=0
Van mesh be applied to donit

It may be a little late, but here is the reason. A voltage source turns into a short, because the internal resistance is 0, whereas a current source disappears because the internal resistance is infinite. I don't know exactly why, but that is just what it is.
Couldn’t you just use source transformation to simplify this. Seems rather tedious using pure nodal analysis
is there anything that you can't teach. 🤯🤯
woah i’m kinda early
