GCSE Physics - Intro to circuits #14 

Hey cognito can you add Cambridge physics to your website if you can thank you

Ri8 agreed !!!

Same

Thanks Jaycee, glad they've helped 👍

👍

Hey shining!! Great to hear you’re finding them helpful 🙌 little and often I’m sure you’ll smash it :)

You’re very welcome - really happy you’re finding the vids useful 👍

Ah thank you so much, really glad to hear the video was helpful 😊

1 hour left, 0 revision done, am i cooked

@@osaka7086 i smashed that test

me 2

Yes😅

My exam is tmr and I have just began studying now😅😅

Thankyou, glad you're enjoying them 😊

Thanks for leaving us a comment! Really happy to hear it helped :))

Wow! You actually replied, this is amazing! 😊 Anyways, I should thank YOU guys for making free-learning accesible for everybody in RU-vid, you are the real heroes, and probably many people have understood some concepts thanks to your videos. Keep up the good work, and have a nice day! Btw, how did you come up with you channel name, I still don’t get it?

Nice

Glad we could help! 😊

Thanks Ali 😊

uh so im gonna just jot this down.. the information in the video is correct, since that is what the gcse physics book has in it- if that what ur teacher said then you might wanna confirm again

Kyzick paha

Kyzick yep

Pain

yuuuuuuuup

meee

Me too, i’m confused on why we are learning the wrong thing and have to approve of it

Here's two things you need for motivation: • somewhere you wanna be (e.g get a great grade like a 9 so you can have the revision skill to get great a-levels and you can get into a great university so you can get a great job so you can live a satisfying life happily and died happy) • and somewhete you don't wanna be (get a average or bad grade e.g 4 then you don't have the work ethic to get a good a level or you may have to resits back tracking your life by a year then you don't get into a good university you parents are disappointed you get a mediocre job you don't like you and then your just sad) Hope that helps to motivate you 😊

i thought you used 9-1 at GCSE? and even at A-Level wouldnt it be A* not A+

this might be a bit late but when benjamin franklin rubbed a tube with a cloth and touched it, he discovered static electricity, he assumed that the static forms when the electrons from the tube is in contact with our hand which has no electrons. After this discovery, battery brands changed the negative and positive symbols on the sides according to his discovery. but joseph thompson found out that when the tube is rubbed by the cloth, the cloth takes away the electrons from the tube, so it has no charge, when a human touches the rod they get static electricity because their electrons are transferred to the rod. but because most battery brands already made everything according to benjamin franklin's theory, nobody changed the design of the battery to the correct way which was negative -> positive. so every battery brand still labels the sides wrong, the positive and negative signs need to be switched in order to be factual. this battery design is called conventional theory. so when you're drawing a battery with a circuit, you should draw the electrons as if they come from the positive side to negative, but when they ask you to answer in words as to where the current flows from and to, it should be negative to positive. so, the drawing of positive to negative because of the battery is labeled as conventional current, which almost everybody uses to draw. i hope this answered it.

ahhh i'm even more confused

i agree it is clear

how did it go?

Same

Tell here

lol i'm in grade 10 we learn this stuff 😂

@@Khushi-qo6qx my cousin also learned it in grade 10 that’s I was asking I guess I’ll study college stuff in grade 10 😆

@@savagex_2008 i am in grade 9 and learning this looooooooool

@@savagex_2008 why do you say 'grade 10', its 'year 10'

I’m cooked it’s today on 4 hours of rev 🫡

Hi Yusuf, what we’re saying is that in reality, electrons flow from the negative terminal to the positive one, but due to historical convention, exams expect you to write that current flows from the positive terminal to the negative. Hope this helps :)

@@Cognitoedu bruh thats so confusing :C thankyou for explaining it

@@Cognitoedu is there a reason they kept this convention, besides simplicity?
