GCSE Physics - How the Electric Motor Works

my hear me out is this cognito voice over guy

My teacher literally never showed up so these videos are my life saver! Mocks’ tomorrow and I didn’t know shit about this but now I do :)

Hey man!
Well represented.
I'm just curious how can one make such videos. Was it your annotations or anything. Even I would love to create videos like these!❤🎉

Oh my gosh amazing video 🎉😱📹

I’ve been confused for weeks but I’ve finally understood it!!

Hi i have a question, i watched another video and it was saying that the rotation stops at 90 but this video says it stops at 180. when the commutator is used, does it flip the current when the wire reaches 90 degrees or 180 degrees, i heard that momentum is what carries it to 180 but im not too sure

حد ثانوية عامة؟

I have a question tho, instead of using a split ring can’t we just use AC current so that it alternates?

this is a wonderful explanation, and makes a topic that is really so difficult into one quite simple! thank you so much, cognito!

bro should teach at my school instead 🙏🙏🙏🙏🙏

THANK YOU SO MUCH YOU SAVED MY LIFE THANK YOU SO MUCH

Okay sir but how does the commutator keep the negative and positve terminals alligned coreectly for current to flow in only one direction?

anyone from IEB Hatfield Online school?

i am so cooked

i didnt have a clue on this topic but this video was an absolute life saver

saved my life before tomorrow

Thank you

i love you man youre saving me right before my tests

We use this WeiRd deViCE!

I’m in 7th grade I don’t understand anything in the book but ur vids the best

Good video my pal

as a science student idk what i would do without cognito, they deserves more recognition 😭

Omg, thanks so much. After watching a few videos in order, I have this satisfying feeling of understanding ❤ subscribed , fully deserved

Y'all teach better than my physics teacher

So when the current reaches the end of the plot ring commutator does it jump to the other side to prevent switching of terminals

i love you

Better than my physic teacher

thank you for this

Excellent work

Which app do you use for editing?

bro i love you so much man

Best explain video ever although I had to watch twice to fully understand thank you 😊

Amazing video.
I can't believe it took just 5 minutes for me to understand a concept that I spent nearly a year struggling to understand it.

I got my test tomorrow and u literally saved my life 😭

Thank you. It really helps to understand the topic ☺

Physics paper 2 tmr and this literally saved my life i didn't understand this topic for the past year till i saw this video thankyou soooo much!!❤️

Thank you so much, my teacher literally skimmed over this whole topic in class and this well explained and concise video really helped me understand this portion of the course before friday's exam.

so how is this different from an ac, I mean if the current keeps changing, shouldn't it be called an AC motor ?

im not even revising im learning

Brilliant❤ so helpful honestly

Bro u need to open a school

doing the LORDS work my guy !!!!!

So does this mean then that the circuit attached to the commutator rotates alongside the coil to keep it moving?

defo one of the hardest concepts to grasp in gcse physics but you explained it so well :)

love ur content

Thank you very much 🙏🏻
