- When an alternating voltage is applied to a purely resistive circuit, the current can be calculated using Ohm's law. We find the current also alternates in phase with the voltage.

great video thank you probably you are the best teacher i have ever seen really i learn so many things watching your videos than electroboom keep it up
The ordering of these videos is all balls.
We are eagerly waiting for future videos.
You answered all my questions about this subject. thank you so much!
Not even joking, ur the best physics teacher on UA-cam, and I’ll give u the reason why you are, it’s because just exactly how I’m explaining to u all the reasons why u r the best, you do exactly the same thing, literally explaining EVERYTHING.
Thank you so much for clarifying the i_o vs v_o graphs. I was confused as to why the i_o graph has higher amplitude than the v_o graph. So it's really just arbitrary, as i_o can have lower/higher numerical value than v_o depending on the resistance.
Physics means Mahesh sir.
Absolutely the best physics teacher in UA-cam.
Thank you sir
You made physics so easy and interesting for me
I don't have enough words ro to express gratitude
You deserve a Bharat ratna award❤ your teaching
Great explaination.
The current max. value must be less than that of the voltage max since r must be > 1
at 7:54 sir i asked you this question in your lcr oscillation video😀
Yes, thanks for asking!
Sir, just a minor mistake, in the graph of i max and v max at 6:37, the wave of v max should be higher than that of i max. It’s just marked wrongly in the graph you showed sir. Thank you for such classes, in love with them

That’s some great help but I’ve already watched the whole video and I thought I addressed my doubt to sir and not anyone else. Thank you for your effort though 👍
Thank you to whoever made this brilliant video, our teacher taught us this but you explained it really clearly, god bless you
just wow!!
i'm so grateful for your videos
Help full .
Absolutely WONDERFUL EXPLANATION
high-quality video and explanation, thanks!
thanks to your help.there is no any video you made i don't understand .l sincerely ask You to make video on:-bimetallic strip
-working of refrigerator
-working of manometer
-working of van degraaf generator
-stable ,unstable and neutral
equilibrium
again thank You for your good response .
Sir , Watch the graph in Ncert , V is above I in y axis
Such clarity. Wow. Thank you so much . Liked and subscribed !
Thanks for the video!
Wow awesome explanation thank you
Sir please put them all ac video in sequence
Salute ur teaching talent sir
One question i have though, is why the amplitude of the current graph higher? Does it mean anything?
Thankyou
Thanks
thank you so much best out of all
i remember after just seeing it once
thank You sir
Sir yesterday I asked you one question in your infinite large charged plane sheet video that can we use a cuboid instead of cylinder placing it the same way as of cylinder...sir please reply
Yes!
@@KhanAcademyIndiaEnglish OK thank you
thank you sm
Resistance changes along the sine wave, with increase voltage, that explains the variation of current having a higher increase with higher voltage
Playlist link please
And tada we have understood the concept
why do dmms use dc through a resistor and not allow you to use ac for certain tests like testing body skin resistance.
You are godfather of physics also better than alakh sir. You are truly best science teacher in world
I agree but don't compare 2 teacher belonging to same field, Goodluck friend.
@@ancientboi why not compare 😅
Isi ka numerical bhi krte to kitna achha lagta
1:00 I also😅😅
The indian guy on UA-cam that everyone was talking about is real
First comment
Thanks sir 👍
At 6:52 min, in the graph the value of i(0) is shown to be greater than that of v(0).....shouldn't it be less than v(0) as i(0) is v(0) by R
sry my bad😅😅😅
2nd
Plzzz make video of Mole concept sir 🙏🙏🙏🙏🙏🙏🙏🙏
Sir can you explain briefly about voltage or current can be greter than between them plz explain it briefly
Thank but pls do calculation on ac
Containing resistance only
1st
How can current can be bigger than voltage? Thats wrong...
