RL & RC Circuits

[@stevenzmanx]

I like how savage this dude is. "I don't like to memorize anything so I derive it". This guy is the realest in the game.

[@nibzlegend99]

Makes sure everyone got a cheatsheet too

[@collinseib]

Really good instructor, very nice work. I thought I should point out a mistake at 9:10 mark he adds the two inductors, it should be 11/3H, not 8/3H, as the left hand inductor is 3H not 2H.

[@lyricalbrain2743]

Exactly

[@kpro-ke5hd]

yeb🎉

[@ebarbie5016]

This is is a great example on how NOT to solve simple RL/RC circuits. When you have a dependent source parallel to a resistor that carries the dependent current, the two are equivalent to a simple resistor... I took me 5 seconds to get the solution just by typing a key sequence into a calculator w/o having to write anything down...

[@joejoe2221hzi]

Love how this guy doesn't rush through explanations and shows every step !

[@haikal1680]

2021 and im still watching his video

[@bossmanbossman-iw7qc]

I’ve learned more here in 30+ minutes than I have in a month of lectures… amazing. Thank you so much! Just something about this lecture video that makes everything feel easy… unlike my professor, who messes up 3x per lecture and loses my attention.

[@SpoodrMin]

curious, what school? I have a similar situation

[@averagegamer1462]

on 9:30 it should be 11/3 not 8/3, I believe, no biggie.

[@gaurisethi5808]

yes it is 11/3 = 3.66

[@ronricogarcia3216]

you're right. He got confused...

[@marwansalah4910]

Mr.Zahi your videos have been saving me through out the semester thank you very much

[@hammamziadeh4093]

Your teaching skills make it easy for students to understand difficult topics. I admire your teaching skills sir, wish I had you as a teacher.

[@josuegialis8146]

You are amazing! I wish I was in your class. Thank you for saving me a couple days before my final. Your videos continue to help people to this day!

[@suhailasami2844]

at 9:30...shouldnt it be 11/3?

[@samynashabeh]

Yes, it should ..

[@sarba85528]

Yes you're right. it should be 11/3. I see that too

[@huntar44ntokzin]

where could one acquire that cheat sheet?

[@sajjadulhaq4136]

wrong solution ..there should be 11/3

[@realaxis2562]

sajjad ul haq u can chk kzbin.info/www/bejne/nprTnJynd6eNbs0

[@meghb.5003]

Could you make a video for the case when we have two switches?

[@ahrar9919]

awesome video clear conceptualization

[@gaurisethi5808]

finally concept got solved , thnku sir :)

[@Janakiram_999]

Hi

[@kesavareddyshiva9206]

at 9:31 it should be 11/3 not 8/3 bcz 3+(2/3)=11/3.i think so sir

[@muhammadahmad96]

Sir, you are the Best!! May Allah(SWT) bless you!

[@vtgaming9204]

+Muhammad Ahmad ALLAAAAAAHHUUU AKBAAAAAR

[@muhammadahmad96]

Bro, do you know what Allah u Akbar means? It means "The Lord is Great" Don't you think that our Creater, our Sustainer, is the greatest of all?

[@muhammadahmad96]

+VT Gaming Ohh.. come on. Be a little respectful. He is not just my God. He is your Lord too. We all have the same God. And kindly think open mindedly without the media's propaganda influencing you. Read Quran... you ll surely dind numerous scientific facts mentioned 1400 years ago.. facts that have been found only very recently by scientists. some of them are: 1.The expansion of universe. 2.The fact that Sun is not stationary. 3.Moon has no light of its own. 4.Embryology 5.The sending down of Iron from Space. 6.Mountains as pegs. 7.The Ozone layer. 8.Space and time theory. 9.How honey ia made (The scientific method) 10.The Big bang ..... and numerous more. thank you.. i hope you ll enjoy reading Quran.. :)

[@parkerflop]

May Allah forgive us and guide us and save us from the fire.

[@vtgaming9204]

Muhammad Ahmad Lol, i'm not going to sit here and debate fiction regardless of predictions it has made, i'm stating that it's cruel and one evil religion to follow. Nostradamus, if i've spelled that correctly made many predictions about the future, he was not religious to my knowledge and we don't see us calling him god due to the fact that he predicted world war 1, 2, and the build up to world war 3 with accuracy down to the president's years before any of this happened. Is he a god now?

[@univerlearn]

Thank you, you made the question easy

[@jadhajali2804]

"just the equations are uglier ! " lol hahahhaha

[@ridwanhusainishraq]

Product over sum which formula does it hold? Didn't get that

[@yosefkashkoul3472]

so nice pop hehehehehehe thanks dr zahi haddad it's seems like your an arab so شكرا كتير اهم اشي البوب هيهيهيهيه

[@awesomestuff8819]

Thank you! You're awesome!!

[@BelayBirhane]

But i am confused cause dor t greater than zero inductance will be open ckt

[@adilbekzhumabekov8303]

Sir, YOU ARE THE BEST!

[@g-xills7010]

which pen you have ?

[@richie1603]

Soldier attitude , dig it !

[@rezashah91]

thank you. it was great...

[@Daniel-rm6hj]

Amazing, thank you so much!

[@loghmanhashemi2480]

at first thanks a lot for good and nice training but i have a question why you ignored from 8 ohm resistor when t>0 ???

[@lwallace758]

When the switch is open, there is no current flowing through the 8 ohm resistor. There for the 5A source and the 8 ohm resistor can be ignored from the circuit. Hope that helps

[@loghmanhashemi2480]

thanks very much bro

[@alaazedan3794]

amazing thank you

[@nikai_ryosuke_2199]

What are the pens are you using?

[@shibadhamija4305]

superb sir ..thnks

[@ohmakademi]

thank you so much...

[@julesmendoza3096]

sir in the last part, i got confused because when I tried to calculate 1M *(2.5/8000) what I get is 3125 and not 312.5

[@davidemelu1142]

where can get the cheat sheet?

[@albiaclifordjanernib.5072]

3+⅔=11/3 for Inductor total equivalent

[@LazyMan1453]

What I should do to find i sub 1 if i can't find i sub 1 in terms of i sub L ?

[@cook1emnstr176]

@4:42 ish...Maybe I'm wrong but when you combined the 2nd set of resistors you forgot to multiply the (24/11) by 2 on the top. The resistance would be ((24/11)*2)/((24/11)+2) = 4.3636/4.1818 = 1.0434 ohm...for real though...please let me know if I'm wrong here...

[@OmErgeVU]

You aren't trying to find the voltage there, you are trying to find the current.

[@amrnabil4508]

very good

[@ahrar9919]

it should be 11/3H not 8/3H

[@hananabd2224]

sir, i hope you make vedios for electronics :( you lectures so helpful :D

[@angelcuellar6613]

You saved my ass, thank you!

[@harikrishnakande4292]

excellent

[@tebogo4716]

Helpful indeed!

[@eric-jd1yl]

sir i think I1 at 0 different than IL at 0 so the equation for I1 (t) you need to find I1 at 0 then put it in the equation?.. im a student.. just asking so mind me if im wronf

[@wilmiecostiniano594]

i also agree

[@user-ry4ee4ev5u]

감사요..덕분에 좀 이해할수있겠네요

[@oguzozum887]

sir you sound like mark hamill (joker)

[@andrewsaba2158]

You sum inductors in series ... 8:54

[@aaronrasmussen16]

Very helpful thank you!

[@mohammedferoz4178]

thank you so much

[@micaelascanlon8761]

forever wishing my lectures were just as rich as his youtube videos my professors are so useless.

[@SaadSheikh-uw6ew]

helpful indeed but you thought that was 2H inductor but that wasn't 2H LOL

[@loghmanhashemi2480]

what the students doing in class men????????

[@tahaadel1718]

?what this guy name

[@loaikhaseeb1251]

Can I get the sheet as a pdf ???

[@DaLeR080]

Окси форева!

[@tylerwilson2280]

ty

[@bencam6720]

thank you

[@preme4371]

I dont get t, if yhe general form of RC circuit is v(t)= Vo e^-t/RC. Then you never get the final answer as yours.

[@cansnyollar5098]

The formula you are talking about assumes there are only a capacitor and a resistor but in his question you also need to account for the current source's contribution. The formula you are talking about also comes from simple 1st order diff. eq. I'd suggest you to stick with this proffessor's method

[@peruboyjose]

30:30 shouldn't that be (2.5/8k)/1u?, which would make alpha 3.125*10^-10?

[@Peter_1986]

"Cheat-sheet". Haha, clever.

[@anugrahsingh1365]

L is 11/3

[@nibzlegend99]

@9:35 should be 11/3 not 8/3

[@Janakiram_999]

Yes

[@muhammadsabih4896]

Thank u so much :) made me clear :)

[@RohanNair32]

The fornula for RC is Ke^-t/ RC. Using the formula for RL i was able to get the first example correct without derivation but i get like e^125t when doing the RC example with the formula. Is there a reason for this?

[@richie1603]

Im confused on the same thing , using the formula too , tricky !!

[@ergikaso9132]

Maybe you found the R wrong there because there is a dependent current source that cannot be killed

[@shashankpandey1966]

its for dc or ac ?

[@abdallahmelhem9358]

If i see a switch then it is a DC?

[@farawayskies]

Can I get that cheat sheet :D

[@mynoobmw3]

where can i print this cheat sheet off? :(

[@mattdouglas8900]

You don't need that exact one... Google it to find others, or better yet: learn some diff eq. I would suggest Paul's Online Math Notes as well as PatrickJMT here on KZbin.

[@mynoobmw3]

Matt Douglas I alrdy took ODE. I just want to find one for reference just in case I need to look up something sometimes
