Discovery of the Electron & Oil Drop - A-level Physics (Turning Points)

[@alanfaraj3450]

what the hell? why aren't you more famous, this literally is free education and you sir are a hero. Thank you

[@adnanmahmud8691]

Exactly

[@timothychinye6008]

I think it's mostly because people don't usually subscribe - but he should be getting views. He should try towork with Physics Online. Physics Online (formally "A Level Physics Online") was in a good position because "A Level Physics" is a very common search term for those in A Level, trying to learn Physics. So by default, he was at the top of search results, thus making him 'famous'. "Science Shorts" on the other hand, doesn't have that kind of advantage, so imo one of his best options to grow is to collab with people like; Physics Online, The cat lady, etc. Maybe the non-school related science people like even Physics Girl, Veritasium, etc. But growing entirely based on straight-up UK School science lessons will take some time.

[@ac3boy1992]

I love the way you taught us a flawless method of working something out then followed it up with "its a bit redundant" got to love that

[@MrTVx99]

I understand all the physics but not how to answer the questions.

[@hi44098]

Welp, time to start revision for paper 3 hehe

[@RobloxGOD-ll7mb]

You started revision 5 years before the exam?? Thats commitment.

[@katepatoot]

THANK YOU THANK YOU THANK YOU IM SO SCARED ABOUT TOMORROW I COULDNT STOP CRYING NOW I CAN RELAX XX

[@eranarkin6859]

Great video but the turning points text book from AQA says the droplets in Millikan's were charged negatively by X-Rays and also shows the plates in opposite orientation to what you've written. Makes sense since electrons are negatively charged

[@jphamspam]

I'd love to see how much of a spike in views you get during exam time

[@ScienceShorts]

It's pretty spectacular xD

[@jacobh1151]

I switched off like 3 minutes in, God help me with the exam on monday

[@alfredchen4579]

It's really helpful sir

[@rohanbhalla3895]

Incredible channel Specially videos on magnetic fields

[@lightx_6584]

i don't even do turning points for my extra module but i like your vids lol

[@goldybindra8785]

12:57 you said that oil drops were positively charged, but shouldn't they be negatively charged to find the charge of the electron?

[@calmz6278]

the polarity of the charge doesnt matter in this case becasue they arent moving anywhere, thats what i think

[@DestinyVideosHD]

5:01 can someone help, I don't get why the force is downwards, because isn't the current flowing from + to minus so from top to bottom. So I get the force to be moving rightwards, obviously just looking logically you can tell it goes downwards but using flemings left hand rule I don't get how you'd get the force to be downwards. Thanks.

[@DestinyVideosHD]

Melawinning __. Hi thanks for the reply but I still don’t understand because the field (index finger) is going from up to down, the current (middle finger) is going from right to left, so the force (thumb) is coming from out the page. So it’s like the force in reality is in the y-axis but using Fleming left hand rule the force is in the z-axis. Hope you understand what I mean. Thanks

[@williampoizer3730]

@@DestinyVideosHD You have to use Flemming's right hand rule. The field is into the page, the current is from left to right (movement of particle) and therefore the force is downwards.

[@g4m3rsye11]

@@williampoizer3730 hi, You don't use the right hand rule because its not a dynamo effect you are observing, its the motor effect. The current is moving left to right but we need to take conventional current into account, which means that the electron flow in the opposite direction to the current that's why the force is downward. Therefore you have to use the left hand rule.

[@bewgamings]

What? me? nooooooo. I would never be doing last minute cramming for paper 3 tomorrow. I did this to myself

[@kiransteward5387]

At 12:10, you said they compared the specific charge with a Hydrogen ion, which is a proton which surely wouldn't have been possible if they thought the atom was spherical and indivisable.

[@magn8195]

great video

[@georgebrash1426]

Could you make some videos for the AQA astrophysics module?

[@adityamisra8869]

Now I got my exams in 1 hour and 20 mins

[@peterblack1712]

is the idea of thermionic emission also linked to ionising atoms in the gas? Thanks

[@the_hasnat]

absolute madlad.

[@plancktime1943]

Great video, thanks.

[@Ilya_012]

Thank you❤️🥺

[@michaellinton7098]

I'm a bit confused about the force due to the magnetic field. Would the force due to the magnetic field not be in the up-ward direction in the first example?

[@ScienceShorts]

+Michael Linton Nope, because conventional current is going to the left.

[@michaellinton7098]

Thanks

[@star-sl8wv]

do we need to know this indepth for ocr physics

[@999Tutorialz]

Very good video, thank you.

[@abitappenden9515]

Would you consider doing videos on the other optional models for AQA like Astrophysics?

[@periwinkle98]

I'm confused about the glow around the cathode bit? I was taught that the glow was observed behind the anode, is this incorrect?

[@nathacle]

I wouldn't worry about that, I don't think it'll come up tomorrow. But for clarity the glow does form around the cathode, not the anode

[@AliAbdullah-bg9gj]

[@moket.2201]

Do we only need to know one method of determining e/m for AQA Physics?

[@moket.2201]

(Revising for Paper 3 - Autumn exams) Also thank you so much for these videos, I have no teacher so your videos have been lifesaving.

[@adityamisra8869]

got my exam in a phew hours

[@Ilya_012]

Love you😘

[@louishink9681]

Can you please make a video on electric field and gravitational fields, it would really be helpful.

[@justaracoonchillinginatoilet69]

yessssssssss

[@elliotverry730]

Anyone else still find this just too hard?

[@MrTVx99]

I understand the physics, I don't understand how to answer the questions
