[@bongshal1472]

U r the best tutor i've ever seen.... When circuits act like boring... Ur expression makes me high😇

[@thisguyispeculiar]

I finally understand the graphs for resonance. Thanks a lot!

[@user-pj1wv1ns9x]

Ye dude this stuff got me confused

[@debasishshaw8788]

I too agree with you 🎉

[@selvoselvo1]

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)

[@anubhav3955]

your explanation is amazing bro .Thanks a lot man

[@ammarkhan2927]

This is very clear and excellent explanation!

[@ajaykumargiri1]

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,

[@coucouj2781]

Well explained. Logical and concise.

[@harshvardhansharma9293]

For me you are the best teacher of physics.

[@vishwajoshi17]

Excellent explanation, thank you sir, didn't expect anything less from KA

[@if4772]

Good for those who just started to study.. This one..

[@dalchandsharma1737]

Very accurate animation .....he even considered the phase differences between current band voltage quite accurately...

[@prachiadhana3806]

Great explanation with great animation 👍🏼 ❤️ wonderful

[@shamirajsurvase8032]

I like how you matched the phase angle in the animation at 9:48, being very precise huh.

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.

[@sokka90ml]

Yeah, see i° and f graph, only in resonance you get maximum current, similar in oscillation and waves

[@Human-sf5ri]

Half knowledge is more dangerous bro 😂😂😂becoz at resonant condition the amplitude of current attains a peak value

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. 09:53 At resonance, a circuit behaves like a pure resistive circuit.

[@whitedaisy2263]

The impedance should be √R^2 + (XL-Xc)^2 .... I didn't understood why sir used Xc - XL....

[@Kashitokaru.]

There are two cases. First when inductive reactance is greater than capacitive reactance ie,(Xl-Xc) is used and vice versa.

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))

[@jagruti_b]

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.

okay all that is awesome but where did we got the value of impedence from ?

By solving circuit equations.

[@PrabhjotSingh_24]

depends upon the ac generator

Sir there is no video regarding impedance sir 😶😶 anyone please paste it ☺️

[@PrabhjotSingh_24]

in the third animation, current can still not be higher than the voltage😅

[@KhanAcademyIndiaEnglish]

I always had that confusion myself, but remember current & voltage are two different quantities with their own units. So, they cannot be compared.

[@PrabhjotSingh_24]

@@KhanAcademyIndiaEnglish but in accordance with ohm's law I think it should be smaller, please correct me if I am wrong

[@KhanAcademyIndiaEnglish]

@@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.
