GCSE Physics - Static Electricity #24

This video covers:
- That static charge builds up on non-conducting materials by the transfer of electrons
- Static charge doesn't normally build up on conducting materials, but can occasionally
- When static charge is discharged it can cause a spark

General info:
- Suitable for all GCSE and IGCSE courses
- See below for whether it is higher or foundation tier for your exam board
- See below for whether it is triple or combined for your exam board

Exam board specific info:
AQA - Only triple science (both foundation and higher tier)
IGCSE Edexcel - Only triple science (and only higher tier)
Edexcel - Only triple science (both foundation and higher tier)
OCR 21st Century - Only triple science (both foundation and higher tier)
OCR Gateway - Only triple science (both foundation and higher tier)

I’m having a exam tomorrow and this actually helped me a lot I appreciate it may Allah grant you a place in jannah inshallah

[tejasbell]

Thank you so much Cognito! I learn more in a 3 minute video than a 1 hour class!

[WTSkyDrago]

I have trouble staying focus in class and this really helps when I am learning this stuff in class and then I forgot it sometimes, so thank you so much :)

[vimathwathsuka]

I’m having exams day after tmrw and this helped a lot

[riki]

very helpful, thank you i have a physics mock tomorrow and this explained the topic very well :)

[isitreallyclosure]

This was really helpful, thank you! I'm a Swedish student in year 8 and I have a very hard time learning anything that my Russian teacher is trying to teach, she can't even speak the language completely and she tells me to ask other teachers for help. BIHHHH I came here to learn from you like gosh!

[moralzombiez]

thank you for these im homeschooled and rlly need these for science (of course i use workbooks and such, but they dont give me the rundown on how these kinds of things work so i have to rely on youtube and online media)

[there]

I have never understood static electricity until after watching your video, thanks a lot

[youxieshazi]

VERY HELPFUL VIDEO. Pika my junior school physics skill in litterally a minute!

[justsomeone]

I've got my last exam tomorrow and this is so helpful! thank you!!! 💕

For metals, how do the electrons flow back?

[Eman-exnd]

U guys are awesome!
Thank you so so so much!!
You guys deserve more subscribers! Hopefully 10million!! You guys deserve it!😊😊👍🏻👍🏻👍🏻

[t.a.n.g.o]

thank you so much, I have my exam tomorrow and this really helped

[caavery]

i cannot shut up about how great this channel is

[theonlyplanetvenus]

this is saving meee, i have a test with static electricity questions tomorrow

[musicvenom]

Best educational video on YOUTUBE about static electricity! *But i have one question*
I have a possitive charged material, and the material touch the conductor. Electrons from conductor go straight to the possitive material?


And also if i have a negative charged material, and the material touch a counductor. The electrons from material go straight to the conducotr right?


I have seen a video about walking on a carpet, and the body give electrons to the carpet. And when body touched conductor,
he got schock. And then again similiar video but then the carpet give electrons to the body.


So there are to possibilities how to discharged the positive or negative material. Connect that to the ground. OR touch the conductor right?

My teacher only knows how to do fashion probably and this vedios is really helpful ❤❤❤ Lost of love from Pakistan 🇵🇰🇵🇰

[linasaadani]

Thank you for the video! It really cleared some things up. I just have one question. In my text book it said to discharge a charged conductor, you should earth it, as this would cause the electrons to flow back into the ground or back up (depending on its charge).
1) Does this work for insulators?
2) You said in your video that conductors don't get a build up of charge. So why is this question asking me how to get rid of a build up of charge? And why do we need to earth it if, according to your video, the electrons just flow straight back to the conductor???
Please reply!

Anyone else here because their teacher made them watch this video? Maybe Ms. Sansing or Mr. Cruz???
