How circuits REALLY work!

Let's deep dive into how a simple electric circuit - a battery connected to a resistor - really works! What happens when we just close the switch?

this is the type of intuition I always hoped in my physics journey. No one ever talks about this stuff. Not even in grad school. What a huge disappointment, really. thank you for your energy!!

Firstly, let me thank you for clearing almost all my doubts about electricity flow and voltage and whatsoever.
I've watching VERISTASIUM videos as well to achieve this but those didn't prove to be providing much explanation required and i never had this kinda intuition before.
I am a 2nd year FSC student from Pakistan who has been fighting issues with electricity flow since this concept was introduced to us in 10th class, finally now i can say that it ends here now that i found such a good explanor.

Although one thing that i didn't understand is that i think it should be negative charge deposited on the surface of other part of the circuit/wire as well and not positive charge.
Tell me where I'm getting it wrong, please.

I'll be waiting to get answers.😊

FINALLY! A Yuotuber who gets it right!!! It's frustrating to see channels with tens to hundreds times the number of views you have, mislead their viewers and subscribers with incorrect explanations.

You deserve way more views. Kudos for explaining this in such an intuitive way.

More deep dives! More deep dives! Thanks! The video answers a lot of questions and is really helpful. I would like a deep dive of the battery where you combine the anatomy of the battery from chemistry with your physics and present it. Once again, thanks a lot!

I remember watching the Veritasium videos "How electricity actually works" and his explanation was not really understandable to me. I watched several more videos from other youtubers but still meh... this is the first one that actually makes sense to me. Thanks!

[theoriginite]

Thanks for this great explanation, keep making these types of videos on doubt that are considered not relevant in school education or exams.

[lycanclawz]

Every time I get to watch your videos, even if am not that focused, everything you say just floats in comprehensively no questions at all. Love it🥰😁

[okoliepromise]

This man needs to be protected at all cost... Such brilliant intuition!!! Thanks for all you do Sir. Please don't stop helping us❤❤❤

[enzoys]

that was THE BEST physics video AND lecture I've ever seen. Really, it culminated and integrated a lot of different individual little knowledges I had and made sense of why I needed to learn all that! I feel like I have an awesome intuition about how circuits work now and even happier that I'm learning about this field

[nadianikitsina]

i am getting asked a lot, why i always try to make things so complicated, instead of just accepting the theory as it is, remember the equation and go on with my life... but somehow i can not...
it is wonderful not only to finally get the answers, but it has been even more valuable for me to recognize, that my questions were not crazy and confusing in the first place and that there is a whole community of people on a similar path :)
i feel at home! thank you very much!
i do not care about the format of the video or its length, but i care about the ideas and intuition you offer!
so more topics about electrical engineering would be much appreciated, since it is not always easy to imaging the invisible stuff :)

I am very happy that you tackled the subject of electrons traveling in a circuit. I have had difficulty finding such high level of detail which includes the "transient stage." You say that initially, the current in the wire is very fast because there is little resistance, but as you know the normal drift velocity of electrons is relatively slow (2 cm/sec) which surprises a lot of people. It may have helped to compare the slow drift velocity of electrons to the velocity of the electric field, which is established at the speed of light. Also, I think that it's important to point out that just like in a resistor, the electrons moving through a wire also bump into atomic nuclei and move in lots of random directions with the net movement being in the direction of the field force. I know that you cover this in Khan Academy videos and thanks for mentioning me.😁

[howdadogdoin]

this is the most incredible channel ever

[Smmmile]

Brilliant, should be a video watched by all students.

[tsmanjunathabhat]

I would listen to you all day long and still be interested. Because I know I will be satisfied at the end to have a better intuition of reality. You are awesome!,

[vinod.tanwani]

You are a saviour to students but honestly more so to hassled parents, who despite all their degrees fail to answer the queries of their child satisfactorily!! Keep making such deep dive videos.

[doggokirby]

Please make more videos like this! Very good for EE students!

[ChrispyThomson]

Keep them coming! I’m a very slow learner so 1/2 hour is about right for me. Thanks!

[AATutorsYT]

these videos are amazing man, you don't understand how much this helped me. PLEASE do more deep

[JohnDoe-usrq]

I just found out about your channel recently so I'm a little late to weigh in the question about the length, but since I really like your content, I'd say you matched my preferences 😃.
Anyways, very awesome content and so well explained. Thank you so much for those videos of yours.

My precious 31:44 minutes of my life, thanks a lot😊😊😊
