GCSE Physics - Electric Fields #25

This video covers:
- What an electric field is
- How to draw electrostatic field lines
- Electrostatic attraction and repulsion
- How air can be 'ionised' and how this can cause sparks

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)

This is actually a life saver it teaches me more in 3 minutes than my physics teacher has taught me in 3 years

[ajibeji]

sometimes teachers fail to just slow down for a second and clearly explain a concept properly. you're a lifesaver

The 1st part was pretty known by most of the people but the practical presentation was something else. It was comprehensive and as the last part was really interesting to know how sparks sometimes passed through air. It couldn't get any less easy❤❤❤

Thank u cognito, you helped every student a lot in gcse science.

Been struggling on this topic since year 10 finally I get it tyyyy!

[domesticdsigner]

Why does it go from positive to negative?

[aydonmanuel]

You used a strongly charged metal to explain the relationship between electric fields and air, but I thought metals cannot become charged due too their conducting characteristics? Please someone explain this!

[hareem]

THANK YOU VERY MUCH. THIS IS TOO HELPFUL FOR ME.

[HI_u]

Tysmmm it rlly helped it helps me make flash cards aswell

[MonnaMonkey]

How does the strong electric field ionise air molecules?? I've looked all over google but i can't find an answer 😕

[rede_neural]

Does the field lines really have these gaps between them?

[Aneesah]

Will you be creating a level videos because your gcse videos are sooo helpful.

[big_cheeseE]

thank you so much honestly the explanation in my textbook was so rubbish

[mollieb]

Does this cover content for year 11 higher physics or just foundation ?

[ImBobtheHampter]

Thank you for the very, very useful information that I can use when on school and later in life

[Aneesah]

I love ur videos sm. I am hoping to get grade 9s, and if I do, It will be thanks to you. I’m going to keep commenting this until I do my gcses and hopefully by then you will see and receive my extreme gratitude. Tysmmm. 👏👏🫶
