GCSE Physics - Electric Fields #25

[@Cognitoedu]

If you’d like to practise the material covered in this video, check out our platform at www.cognitoedu.org - it's totally free, and has been built to make learning and revision as easy as possible. The main features are: - Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown. - Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on. - Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like. - A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts. - A comprehensive bank of past exam papers, organised both by year, and also by topic.

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

[@ajibeji02]

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

[@marvinsingh9960]

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❤❤❤

[@Cognitoedu]

Glad you enjoyed it!

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!

[@Cognitoedu]

Ah cheers for that Shining!!! Really happy to hear it made sense (and thanks for always leaving a comment you’re a legend!)

Thank you so much! I love your videos they make everything so much easier to understand. Keep making these great videos👍

[@domesticd3signer339]

Why does it go from positive to negative?

[@hareem000]

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

[@aydonmanuel444]

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!

[@anuragthakur4341]

Charge can still accumulate on metals

[@tejas.a06]

eg cars can accumulate charge via wind which carries electrons

[@bossman69bossman32]

remember that a metal has postively charged metal ions and since they contain delocalised electrons, they can carry charge. Therefore, it makes them charged.

Really Helpful Thanks 😁

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

[@rede_neural]

Does the field lines really have these gaps between them?

[@serenaalayek8011]

Yup obviously

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

[@Wildest.Dreams.08]

Basically, (just gonna give background info first so it makes sense,) ionisation, as you probably know is when two atoms exchange electrons so the atom that gave the electrons away, becomes positive, and the object that was given the electrons becomes negative. And ionisation happens when an atom has a charge. Now, if the object that is highly electrically charged, and the air around is is obviously not, as the air is neutrally charged, the object strips the air of it's own electrons, but the object doesn't take the electrons, it just sends it off to the surroundings, (away from the static field.) The air is now positively charged as it has more protons than electrons. The object then gives the air it's own electrons, and as we know, when a material like this sends it's electrons off to jump off, it causes an electric surge causing the air to now be electrically charged. I hope this helps.

[@Wildest.Dreams.08]

I edited my last answer, that had some untrue things written in there, because protons never move. Check it out now if you're still stuck.

[@MonnaMonkey320]
