I can’t tell you how much help you’ve brought to me. I’m scoring 90 to 100 on every single physics and precalculus tests. You are the best!
You’re doing this in precalc?
me too bro wow
Good job!😁😁
I guess you don’t really need integration for some of these problems lol wait until the circuit wires themselves have their own resistance 😂 🍀
Imagine how well this guy did in his finals
Man slayed
I heard The teacher asked him for help
He is our valedictorian
His CGPA probably 5.0
nah he made the final
I wonder how a man can not only master all the domains of sciences and math and also wise enough to teach it in a layman language to the world!!! He is so great!
Give this man a medal!
you're the best sir!
This really helped during Coronavirus
why.
Thanks for the Video! Forgive me for the intrusion, I am interested in your opinion. Have you considered - Runayslarn Survival Manifestation (just google it)? It is a smashing one off product for discovering how to repair your electronic items without the normal expense. Ive heard some super things about it and my good mate called Gray after a lifetime of fighting got astronomical results with it.

Explained beautifully
"Feel free to pause the video to try this problem"
- "No, No I don't think I will"
Nah I'd skip
I like his voice... That's all I gotta say. And he describes things well, so I guess I can say he's the ideal tutor
To be honest something about his mic and the way he pronounces his ssss sounds makes me cringe a little
No matter what semester I'm in, I'm always watching your videos for one or more of my classes lmao.
Thank you for posting this. This has been a key presentation. With this example, I am able to see the formula of I / V = 1 /r1 + 1/r2 + 1/r3 in action. I/ 30 = 6/30 + 5/30 + 3/30 = 14 /30.
I literally watched an hour of my professor’s lecture and kinda understood. Watched 12 min of this and I understand it all. Thanks again🤝
Thank you tons. My Professor has been trying to explain this to me, I watched this video once and everything just clicked. I’ve got a test today and I’m more than confident about this topic. You rock
Your an excellent teacher, easy to follow. Thank you this is exactly what I was looking for.
You zone out for 1 minute in class and suddenly you have no idea how anything is happening. Thanks for making this.
we just learned this is class today... such great timing :D
Ur dumb

Thank you! I really like all these circuit analysis videos you've been making lately!
After a long search you are the one to teach excellent
holly shit you just condensed a 3 hour class in 11 and a haft minutes and made it very digestible, well done you did a better job than my instructor
Seriously good, very easy to follow. Much appreciated!
Would love an explanation as to what negative voltage means and how that's possible.
Thanks, i strugguled with this concept for a while x)
Thanks so much I understand this clearly you explain better than my Science teacher 😊
Another method to do this without getting the current is to get the percentage. For example, R2 is 3 ohms. You would divide 3/R1+R2 = .6. Now multiple the .6 by the voltage of 20. It should give you 12V. That's the drop for R2. You can do this with as many resistors in a circuit.
P.S In a series circuit.
It all clicked when I watched your video, thank you!
You are a good teacher! slowley explaining with the right rithem. thanks
I was just thinking to give you 1000 like but could give you only one which was 251st
Wonderful explanation. I'm very thankful to you, cleared all my concepts
Thanks for the help man, you were straight to it and precise... appreciate it!
No problem
Have my main exam for level 2 tomorrow been watching these for practice and it’s amazing thank you 🙏
hey, thank you for this video im an apprentice lineman and this expalined it to me crystal clear.
From organic chemistry to integration, number system to statistics every time I have a problem this guy has an answer.
This is what I wanted, you did it dear, well done sir and Thanks for such great explanation.
Love from bangladesh brother .. this video is very helpful for my today assignment
Thank you so much after seeing these videos I finally understand circuits and I have been exposed to them in 2 different college level physics classes (with labs!) before the class I am in now.
Why would anyone dislike this video?
This was immensely helpful thank you Sir more is thee due then all can afford to pay.
Hi bro your way of explanation is very nice
Very Important question!
The additional battery sources are fuckin me up
Excellent demonstration thank you very much. If possible pIease explain in the same way in a parallel circuit
Regards Joseph
Coming in clutch for my at home open book exam.
You r a best teacher 😃🙂 . I am really excited for next videos.
Thanks a lot, you helped me understand more about ohms law and how to use it.
LIFE. SAVER.
Bro how are you a better teacher than my EEE202 prof?
Such great content! Such a God send, thank you so much!
Ever sience i watch this video my component on DIY project never exploded anymore thanks alot 🥰
Thank you for examples but understanding 🔥
No sir....We are thankful to u 🙏 ❤
Thank you very much,you help me a lot to understand it...
Thanks bro now am on my way to succeed in physics ❤
Weell you are my new teacher 💕 you teach it well 💖
Very nice lecture. Thanks
omg thank you so much this made everything much easier xx
If its in kilo ohm for resistor when finding current do i change unit or what?
Very useful 🎉🙏
You the best man! Can't wait to see more videos from you..
thanks man great explanasion😩👌
Very helpful
Thank u very much
Yoo tysm I'm in exam rn this is very useful :)
thank you it is so easy now!!!
Thank you so much 😊 I’ve been looking for this for SO long
Excellent teaching.
I am trying to find an online calculator for a simple circuit that will allow me to plug in voltage and resistor and give me the output voltage,
So if I have a source voltage of 20 volts and I was an output voltage of 2 volts, what size resistor will I need ?
And as I change the voltage, what size resistor will I need for different source voltages to keep my output voltage at 2 volts ?
Is there a webpage that has this calculator that I could enter the output voltage and input voltage and get the resistor needed ?
Or input voltage and resistor and have it tell me the voltage it will put out ?
Thanks
This is awesome. Great video. Thanks!!
Thanks for this. Polishes some quite rough edges,..one question though Mkubwa (means Chairman), in the last example, that Voltage drop of -65V, how is it possible to combine 50V and 10V to get 65V(just reverse connection)? That defies the Second Law of Thermodynamics
50+10 is 60 tho
It's not 65V. It's minus 65V, so the potential goes from 50V with a 40V drop to 10V, then another 75V drop to -65V. Total source potential = 50 - (-65) = 115V
Why was this a better explanation than my 80 min physics class every other day 💀
Who knew it was that simple
This whole time I thought it was so complex
Thanks this was very helpful
Thank you sir!
Helpful sir thnxs lot
This is a cool video, easy to understand unlike similar creators' videos. Do you think there will be one breaking down a problem where the voltage drop is shown but the individual resistance values are not?
Love you man
perfectly explained thank you
How come 75 v drop ... when we gives 50 v input. Can you explain please
very well understood. thanks!!!
You are a genius thanks
If this bloke was my teacher, I wouldn't get so frustrated during class 🤣
Very informative video. It would be nice to see the full closed loop circuit to see how the potential got to 50V and 10V at point A and B i.e. to cross check that the sum of the potential difference equates to zero.
Thanks, a good explanation. I don't think you even needed to mention conventional current, never mind further confusing things with mentioning electron flow. The calculation to solve for I didn't seem to care about what the electrons were doing?
Your amazing!!
One question, why the current flow in the calculation from postive to negstive?.. while the definition on current is flow of electron which is from negative terminal to postive... anyone please help me to understand this
what's the difference between this and KVL
Sir Please can you upload lecture about three balanced voltages
zanzibar
Thank you so much ❤❤
I have one confusion about calculating the voltage drop. If I need to use a resistor with one led to connect with 220v AC, then I can find the resistor using the formula R = (supply voltage - led voltage) /led current = (220-2)/0.02=11k. And the wattage of the resistor is P=V^2/R = 218^2/11000=4~5W. But how I will know the voltage drop if I have a resistor with a different ohms and wattage values?
Thnk you so much 😭
Thanks u guru ( sir ) for discuss thir problem

What about parallel connection
Please help me... I have a technology question and I have no idea how to calculate it, the question is:Calculate the potential difference (voltage) if four cells of 1.5 volt each are connected in series.
If battery have low marked capicity it is possible to obtain 4 amps from 20 volt battery ?
For instance take capicity 100 mah
You'd have to connect 40 20V100mA batteries in parallel for that. 100mA x 40 = 4A
mAh is a different metric. That's miliamps per hour, which isn't a measure of current, but electric charge.
thank you besty
How can there be more voltage across R2 when the resistance is higher? Shouldn’t there be less voltage flowing through since the resistance is higher?
😂😂😂
Good question. It's directly proportional. The higher the resistance the greater the voltage. What decreases is the current. When the resistance is high the current decreases but the voltage increases.
Can someone help me understand a circuit I'm looking at? There's no current flow in this circuit. On one side there's a +10 V source, in the middle there's a resistor and on the right the wire is connected to a reverse biased diode (hence no current flowing).
Now, it says on this circuit that the potential at point A - which is right after the resistor - is still 10V. So, no current flowing and no voltage drop across the resistor. This is what I can't understand, why is there no voltage drop?
Can you apply this too to a DC voltage drop?
Im in diploma and currently in third sem. And even basic stuff like this I easily forget...
Thanks, mate.
Just took a test over this today lol
Conventional flow = you track holes flow
Electron flow = you track electrons flow that flow inside holes
please sir help when we voltage down through voltage devider so this time current always decreased so our load not better working
Im doing my midterms while watching this hAhhaahha
