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!
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
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 :)
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?
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!
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
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.
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.
