Area vector with examples & flux vector equation | Electric fields & charges | Khan Academy

Let's explore how and why we treat area as a vector. The direction of area vector is always perpendicular to it. For open surfaces, we have to arbitrarily choose between two perpendiculars, but for closed surfaces, we choose the outward direction as our standard. This helps us define the flux to be the dot product of electric field and the area.

Why do i love him so much????? i will protect this man with a blanket and a sword. No fear should ever fall upon him😭😭

[@bkk28200]

I'm ur fellow 🙌🏼

[@konakill]

i've been having trouble mentally getting to lectures. Your videos have been helping me catch up so much! Thank you

[@nathanielkilmer5022]

I love how this dude is doing his best Sal Khan impression. Great videos, btw!

[@Mahesh_Shenoy]

I am influenced by him, but I am not trying to do an impression :)

[@nathanielkilmer5022]

@@Mahesh_Shenoy he's a great guy to be influenced by. I can hear echos of his speech patterns in this person's vocabulary, like they must have watched hundreds of hours of Khan lectures. I can hear Sal's influence in 3Blue1Brown, as well.

[@muslimattar3047]

Man thank you so much. This was really really helpful.
By the way , the explanation is top.
I,m watching you from Iraq yet you made it so basic and simple.

[@ashutosh-kumar]

Thank you sir, watched it on 14th October 2021 at 8:26 PM for the prepration of term 1 board examination 2021-22.

[@karman103batth4]

Same

[@arpitasharma6892]

You sir are LEGIT the BEST. PERIOD.

[@manitechnutsp9106]

U made me love physics
You deserve millions of subs sir i feel really bad

[@manitechnutsp9106]

Sir your voice is inspiring
Your teaching style is fantastic

Khan Academy India can you make playlist of all related videos in a sequence it will be very helpful

[@kiraow8028]

agree'

[@S1ngh1]

It was an amazing experience leraning from you. And it was fun! It was so boring when i was reading my notes but watching this was so much more interesting.

[@sajanphilip8221]

Your drawing is extremely good

[@Nancy_Shorts13]

Mind blowing explanation ❤️👏

[@doinnothing7818]

Can we draw this area vector anywhere on the surface? Or at geometrical centre?

[@carl_johnson_]

Sir its perpendicular to a line
And normal to a plane..

[@FormerlyChainChompBraden]

great video. this helped a TON

[@ananyatyagi7753]

thankyou so much !

[@olaoluwaomopariola4867]

Please can you explain why in some textbooks, electric flux is Φ = ∫ E dA and in other textbooks electric flux is Ψ= Q, and in this video too? Which one is correct and which is wrong?

[@johnn._snow]

Now tell how to find direction for open

[@smiling4813]

But how to find it without the x y z
?
If it is just given like that

[@shivamsuhana6603]

please tell me that for which class this video is related

[@konakill]

physics in electromagnetism I'd assume.

[@mathewmunro3770]

If your area is a result of a vector cross-product, you could define the direction of the area as per the right-hand rule.
