Electric Current: Crash Course Physics #28

Electric Current: Crash Course Physics #28

So, electric current works like a river… kinda… Instead of flowing based on elevation, electric current works a little differently. But it’s a good metaphor. In this episode of Crash Course Physics, Shini talks to us about electric current, voltaic cells, and how we get electric charge.

    That star trek reference though. Why is no one talking about this

  2. Naila Pang on August 30, 2020 at 9:21 pm

    am I the only one distracted by her hair ….like am I trippin ..is one side short and the other long ?

  3. Noor Ul Arfeen on August 30, 2020 at 9:21 pm

    I have set this lady to speed 0.75 ….

  4. Karla Lorena Arteaga Argomedo on August 30, 2020 at 9:22 pm

    great explanation, but the talking is way too fast! My 5th graders had a hard time understanding (and so as me)

  5. BlindingLight on August 30, 2020 at 9:25 pm

    that’s a nice millennium falcon you got there
    can i have it?

  6. Ahmad Mahmood on August 30, 2020 at 9:25 pm

    i have been listening to you by forcefully slowing down your speed

  7. Dindo-luiz Raboca on August 30, 2020 at 9:26 pm

    she goin dumb fast

  8. ReVo GaMiNG on August 30, 2020 at 9:27 pm

    Why do we even use conventional current?
    I wanna ask few things here
    Current is a flow of electrons , current is flowing from positive to negative terminal according to conventional current but now u say that current flow from negative to positive….
    If current drive the electrons then what does drive the current?

  9. Jordan Kong on August 30, 2020 at 9:28 pm

    So much better than the previous episode.

  10. 2021 S2G4 03 CHAN SHING FUNG on August 30, 2020 at 9:28 pm

    why so many borg references

  11. Matthew Wilson on August 30, 2020 at 9:29 pm

    she has a giant nose

  12. Johnny Utah on August 30, 2020 at 9:32 pm

    Jumping around the subject like hopscotch

  13. Benjamin King on August 30, 2020 at 9:35 pm

    I speed these videos up 1.5x😎

  14. Sara Ashlyn on August 30, 2020 at 9:36 pm

    Lol im having to do these bc we aren’t in class to do them

  15. Safiya Harris on August 30, 2020 at 9:36 pm

    Y’all my teacher assigned this to me and it really didn’t help so I just play Roblox XD

  16. Jin Shikami on August 30, 2020 at 9:39 pm

    Diodes, who needs them! Look for: androidcircuitsolver/app.html

  17. MANIKANDAN PALANISAMY on August 30, 2020 at 9:39 pm

    What happens in an CIRCUIT WHEN an SINGLE ELECTRON is PUSHED into the circuit by an BATTERY with some potential difference…. Will electron stop by pushing nearby electron OR will it reach CATHODE by pushing all the electron in it’s way…???

  18. Pavel Morales on August 30, 2020 at 9:40 pm

    Playing at x0.75 rate and still need to pause 😅

  19. KAMRYN YERMAN on August 30, 2020 at 9:42 pm

    Can you try talking slower

  20. smith thapa on August 30, 2020 at 9:42 pm

    I think you should go a bit slow …while you explain…

  21. Mee Beeat on August 30, 2020 at 9:42 pm

    Get a better accent plz

  22. Samuel Ollesh on August 30, 2020 at 9:43 pm

    So we are going to ignore the fact that Locutus of Borg shows up when talking about resistance? Great video!

  23. Ella yi on August 30, 2020 at 9:44 pm

    can u please speak a little bit slower, the video didn’t help me at all…

  24. Catrizia Cat on August 30, 2020 at 9:47 pm

    I= 1C/1s = 1Amp
    V=IR
    P=energy/time= change in charge X voltage/time
    P= IV = I^2R = V^2/R

    Thanks so much this video just taught me everything we did this term

  25. Lushan Todd on August 30, 2020 at 9:48 pm

    Damn she’s good 👍

  26. dolphiintears on August 30, 2020 at 9:52 pm

    0.75 speed is normal

  27. Spruce_Goose on August 30, 2020 at 9:52 pm

    1:54
    Uh what? That circuit would operate fine without that grounding wire. It doesn’t need ‘earth’ to supply electrons. ‘Grounding’ simply provides reference to the system, in the case of earthing, the reference being earth.

  28. Work Out on August 30, 2020 at 9:54 pm

    Why do the people in crash course talk so damn quick

  29. Ayush Mokal on August 30, 2020 at 9:56 pm

    What do you expect dude you have to go through the concept first it’s not in dept explanation of the concept the channel name " CRASH COURSE " LOL You people !

  30. Anmol Daiwajna on August 30, 2020 at 9:56 pm

    0.25 playback speed makes it a sound like she making weird moans while she is feeling paralyzed

  31. Dnyanraj Telang on August 30, 2020 at 9:56 pm

    your system is like open loop system,you do not consider feedback from viewers

  32. Nejat Molla on August 30, 2020 at 9:58 pm

    I love her accent

  33. May Alnajadah on August 30, 2020 at 9:58 pm

    At first I couldn’t understand but if you slow it down to 0.75x it will be good

  34. Arti Garg on August 30, 2020 at 10:02 pm

    You are a genius

  35. Jakob Fredriksson on August 30, 2020 at 10:02 pm

    I had a surprisingly smooth sailing until watt happened. She’s hot.

  36. robert mccully on August 30, 2020 at 10:04 pm

    To fast, what is current?

  37. Somya Jain on August 30, 2020 at 10:05 pm

    she has a lot of potential to be a rapper

  38. Unknown Division on August 30, 2020 at 10:09 pm

    This brings up more questions than answers

  39. RearViewMirror on August 30, 2020 at 10:12 pm

    Congratulations on 10 million subs btw.

  40. Paul Simon Emechebe on August 30, 2020 at 10:12 pm

    TOO FAST

  41. S.p Jejna on August 30, 2020 at 10:13 pm

    Dobar dan profesorice gledamo video

  42. J S on August 30, 2020 at 10:14 pm

    Slow down i dont understand

  43. Kareem Mohammed on August 30, 2020 at 10:14 pm

    thank ya

  44. Sreshta Ghosh on August 30, 2020 at 10:14 pm

    Me reading all the comments saying she talking too fast listening on 1.25 speed 👂👁👄👁👂

  45. Fay on August 30, 2020 at 10:14 pm

    I’d hate to listen to a crash course for more than 15 minutes about a chapter in a textbook. Crash course is meant to be a review or, in my case, to hook my interest in that particular subject. As for studying the thorough concept, I don’t recommend you to watch a crash course. Get a textbook, have your teacher explain to you, ask your friends, ask people on the internet, or watch a thorough lesson online. This channel has done what I expected them to do. No offense to other viewers, just a suggestion and opinion.

  46. aerozg on August 30, 2020 at 10:15 pm

    Editing. You are doing it wrong. We are not machines.

  47. Luqmaan Arain on August 30, 2020 at 10:17 pm

    Can u teach about milikans oil drop

  48. GCSE Physics Explained on August 30, 2020 at 10:17 pm

    Great video! Keep up the content!

  49. Etienne Quillon on August 30, 2020 at 10:17 pm

    Thank you, doctor, I’ve learnt much. Love your RP.

  50. mahbubur rahman on August 30, 2020 at 10:17 pm

    If the speed slows down a little then it will be very…. helpful…..
