So far, it is best video on resonance, all others just start bombarding you with formulas without explaining the underlying logic (which is so more important, because without logic you forget all)
I found no videos on the derivation of Impedance formula derivation so dear friend you can check physics by manjar sir video for reference ❤thanks, it's specifically for class 12th student of cbsc,
Thank you , u saved me from hell 😩❤✅ my final physics is on 28/9/2022 . Now its 18/9/2022 6:35 pm , lets be a souvenir for me .. the last days that i study physics , its the end ❤✅ the first time i knew this channel was on May 2022

Resonance doesn't mean maximum output or maximum current. It is defined as the condition in ac circuit under steady state when current is in phase of voltage.
I didn't understand one point. You said that Vmax is going to be constant if we change w. But if we change the frequency Vmax is going to change,isn't?(because of V=B.A.N.w sin(wt))
They didn't mean to say Vmax is going to be constant. They meant to say how do we get Imax while keeping Vmax constant, so the only thing we can change is w by changing the frequency.
@@PrabhjotSingh_24 Think of it this way, according to speed = distance/time, could we say speed is always than distance? Even numerically, the denominator could always be a fraction.
U r the best tutor i've ever seen.... When circuits act like boring... Ur expression makes me high😇
I finally understand the graphs for resonance.
Thanks a lot!
Ye dude this stuff got me confused
I too agree with you 🎉
Only channel that teach concept detailed to students

your explanation is amazing bro .Thanks a lot man
This is very clear and excellent explanation!
Great explanation with great animation 👍🏼 ❤️ wonderful
Excellent explanation, thank you sir, didn't expect anything less from KA
For me you are the best teacher of physics.
Well explained. Logical and concise.
Khan academy never disappoints❤
I found no videos on the derivation of Impedance formula derivation so dear friend you can check physics by manjar sir video for reference ❤thanks, it's specifically for class 12th student of cbsc,
What a video thankyou so much sir you deserve everything 😭😭❤️❤️❤️❤️
Bro there ia a small mistake
It is xl -xc not xc-xl😊
Very accurate animation .....he even considered the phase differences between current band voltage quite accurately...
Good for those who just started to study..
This one..
I like how you matched the phase angle in the animation at 9:48, being very precise huh.
Yeah just noticed that! Such precision.🤌
Thank you so much for helping me just before my exam.Grateful forever.

how was your physics final??
Enjoyed this session too...

00:02 Resonance is achieving maximum current output for a given input frequency.
01:24 Impedance depends on the frequency in alternating circuits
02:52 Resonant frequency gives maximum current
04:13 Minimizing the number for resonant frequency
05:38 Resonant frequency is the frequency at which current becomes maximum.
07:15 Impedance is dominated by the capacitor at frequencies lower than the resonant frequency.
08:32 At the resonant frequency, the current is maximum and the bulb glows very bright.

sooo gooood
wonderful wonderful explanation!!!
Finally understood this in university
Thanks so much for this!!!
Amazing❤
Very good didactic.
Please make a playlist of whole AC chapter
Loved it b4o..
Thank You !!!
Resonance doesn't mean maximum output or maximum current. It is defined as the condition in ac circuit under steady state when current is in phase of voltage.
Yeah, see i° and f graph, only in resonance you get maximum current, similar in oscillation and waves
Half knowledge is more dangerous bro 😂😂😂becoz at resonant condition the amplitude of current attains a peak value
@@Human-sf5ri current can be zero in resonance.
@@harshrajsingh8969 if potential is zero than current can be zero in resonance
@@Human-sf5ri if supply ac voltage is non zero then current can be zero in resonance.
Best for me,, love it
Thanks
amazing
very helpful
Sir you are great
Can anyone send the link fr previous video
The impedance should be √R^2 + (XL-Xc)^2 .... I didn't understood why sir used Xc - XL....
There are two cases.
First when inductive reactance is greater than capacitive reactance ie,(Xl-Xc) is used and vice versa.
Sir there is no video regarding impedance sir ??😔😔😔😶😶😶

Can i get the link of video where you derived LCR Ac circuit??
Mm I too need it..I couldn't find it anywhere

okay all that is awesome but where did we got the value of impedence from ?
By solving circuit equations.
@@shantanusingh3961 no like he said he explained that in a video , but i just can't find that video
@@endlesslearning26 They've explained what impedance is, in this👇 video

in the third animation, current can still not be higher than the voltage😅
I always had that confusion myself, but remember current & voltage are two different quantities with their own units. So, they cannot be compared.
@@KhanAcademyIndiaEnglish but in accordance with ohm's law I think it should be smaller, please correct me if I am wrong
@@PrabhjotSingh_24 Think of it this way, according to speed = distance/time, could we say speed is always than distance? Even numerically, the denominator could always be a fraction.
@@KhanAcademyIndiaEnglish Thanks, Now i got it
Don't try to actually build one of these and test it. Just blindly believe and regurgitate.
😍
Sir there is no video regarding impedance sir 😶😶 anyone please paste it ☺️

But how do you change the frequency???
depends upon the ac generator
why u r studying ac

I'm here for "Current" not "kharant"
Shoe practically ur theory is useless
