What is RMS value? (& why should we care?) | Alternating currents | Physics | Khan Academy

[@engineer491]

Many of them have knowledge but how beautifully you have served it is rare....Seeing things out of the box and showing different perspective of what exactly happening is a real achievement of gaining knowledge and I felt that today....Thanx....Please keep making videos world need such kind of teachers...I have never ever commented but today was unable to resist myself after seeing few of your videos, you have explained so nicely I am really thankful to u.....

The teaching skill he has is insane ..... Understood clearly

[@dakshbadal7522]

The kind of explanation that puts smiles on students' faces. Thank you

[@jyotisingh4109]

Sir, you are THE BEST teacher ever. You have helped me a lot. Pls keeping making such videos. ❤️❤️

[@TheSymonak]

Damn right! I have to yeach that stuff tomorow, and this made it SOOO much clearer and easy to explain!

[@PierreSophy]

I didn't get a chance to learn what rms really was except that it's relatated to some max value. Mahesh, you have a talent for explaining tough concepts in such a simple way. Another video of yours that come to mind is "Why resistors in series have different voltage (but same current)?" from FloatHeadPhysics. I struggle with learning about electricity but wow do I enjoy watching and rewatching your videos. Its so intuitive that I just want to share this knowledge with others. Thank you so much for your efforts, it has helped me greatly!

[@mcheungtv]

Holy shit, my teacher had taught a whole lesson on this, more than 1 hr, still not a single clue until this guy showed up with just 12 mins

[@TIGREinVOLO]

The best and most effective explanation ever seen for anyone who is not interest into complex Maths rules to obtain an understanding. Well done

[@carbyte2673]

wow,the quality of teaching is good ! I really felt joy while watching this video,thank you sir!

[@polarkerr]

After 35 yrs now I understand RMS thank you

[@natural_klassicart]

seriously??

[@ashrafulfaysal2935]

This guy!!!!! Maaaaaan !!!!! You just can't be that good

[@lillysk6254]

Sir you are just amazing!!!!!...I don't know how to thank you ...you are the best physics teacher I have ever met !!

[@electricity2703]

You explained where this RMS thing come from which is rare, so thank you 🎉

[@puneethnaika]

Like seriously we have been thought something wrong , I have studied same thing and come to my 2nd year of engineering and now I realise the truth.

[@gaurav6823]

i often to say that who is watching and learnng the concept will be genious one day❤you had made science very intresting.... i didnot get tried in each minute..your 13 minute video is equal to alkah sir 1 hr video

[@JohnSmith-ed1sr]

Excellent video…. I was wondering who made this so well then realized it was khan academy… I should have guessed. Only Kahn academy makes videos this well

[@prastuti_413]

Broh! He's teaching us to love physics!❤

[@payalmehta3782]

You clear concepts perfectly.

[@asmakhatoon6691]

Please universe bless Khan academy's teachers with only good things

[@gousiabanu5776]

Sir,now i got an idea what truely the RMS value was.thank you so much sir and keep making such videos .

[@sudiptoatutube]

Truely Awesome Explanation. I got this by using mean value theorem for integrals.

[@radhashukla8114]

Concept crystal 🔮 clear.

[@nankinanko5790]

I love 😍 this teaching method. Story telling ❤ Thanks for this video Khan🫡

[@MartinZimba-su4uf]

This is the best,,thanks professor

I Usually Never Comment....But..Man You Just Made That Way Too Interesting💀

[@KhanAcademyIndiaEnglish]

Appreciate it :)

[@sudmudmud357]

How good was that , you’re awesome 👏 and a great teacher. Keep up the good work, I will never forget what RMS is . We use this parameter very often in vibration PSD representations. From Melbourne, Australia 🇦🇺

[@kingd2king]

Thanks for sharing. It’s the best explanation

[@antinora3265]

You are an outstanding teacher! Thank you

[@harshavardhansai4453]

Really great full sir learning with you. Maximum when i get doubt in electrical straightly I find your lectures to learn concepts clearly.

[@fastusbombastus3040]

brilliant explanation!!! thank you!!! top job!!!

too good

[@rmacademy3971]

Great Job

[@gettynnamso7726]

I wish there was a way to like twice😅

[@karishmakaushik9491]

But not for every sinusoidal current right ? 11:06 I mean when phases are varying ?

[@shivamshrivastava8175]

if we have a value maximum current, then what would be greater i(dc) or i(rms) ?

[@malekqaddarah]

Link to the next video?

[@theknightsky3834]

Fluctuation of bulb is 50 times or 100 times per second? 1 cycle is equal to 2 times fluctuations?.....watched ur previous video in which u described frequency and no. of times alternating current changes direction.

[@hajragul8986]

Sir why should we have to equalise power of DC bulb to that of AC bulb

[@abishekta8797]

Just like replacing 2 resistor in series with a equivalent resistor makes calculation easy. Similarly by replacing a AC voltage with the equivalent DC voltage(with RMS value) makes calculation of power dissipated easy.

[@shreyajayakrishnan7730]

❤

[@balajimundhe763]

BUT then what is significance of average current ?

[@alberteinstien7016]

Sir I have a question if we take two sin waves in same graph with x axis as radians, here one is sinx and other is sin(2x) . Then as they say the complete cycle takes only (2phi)radians. Then for sin(2x),it takes less than (2phi) to complete one cycle if we see in graph because more frequency ??

[@huskiehuskerson5300]

@@inbazhaganravikumar2293 no US uses 60 cycles per second, because they generate current at 60Hz

[@huskiehuskerson5300]

Yes less time to complete cycle hence higher frequency

[@huskiehuskerson5300]

@@inbazhaganravikumar2293 they use 110 Volts, 110 is not frequency

[@sambabugupta1709]

👌🏻👌

[@alberteinstien7016]

So what is the efficiency of this way of representation sir

[@alberteinstien7016]

@sussy Kanye balls I asked about the rms value sir .not about the wonderful way of teaching. that sentence i think is misleading

[@alberteinstien7016]

Rms value in real life in our home, especially for eb bill Are we dissipating more power and only giving less money because they only take the rms value

[@inbazhaganravikumar2293]

Nearly same bro but, they measure in terms of units(1 unit=1kWh-Kilo Watt Hour). So the meter might use rms value for calculation of power dissipation✌️

[@mohankharel3359]

I think it's 220V r.m.s

[@huskiehuskerson5300]

Isn't the fluctuation happening 100 times per second?

[@ralphaverill2001]

I watched twice and still didn't catch it. What is this N value that I am dividing by?

[@melwinonduty]

N denotes the number of cycle that is the sinusoidal graph

[@paromita_ghosh]

Damn got more. Confused wtf Ac or dc bulb duh
