Voltage, Electric Energy, and Capacitors: Crash Course Physics #27

So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, everyone! Today, Shini has the task of breaking down Electrical Potential Energy, Electric Potential, Voltage, Capacitors, Energy Storage, and Potential Energy… it’s a lot!

  1. Useless talking far to fast

  2. Why is everyone complaining about the speed? This is decent – it just summarises everything. From an a level stand point it’s good because it’s refreshing my memory very quickly!

  3. So for a negative charge, would it have a higher potential closer to a negative point charge?

  4. After seeing this video's it like…wait what is meant by an electron???so confusing???? : |


  6. Great information but way too fast! She needs to quit her job immediately and join an under water treasure hunting team her lung capacity is unreal.

  7. im confusion

  8. one of the most confusing video on volts in the whole youtube

  9. It is like she is freestyling physics

  10. Yall saying slow down as if she is going to change during the video lol.

  11. I didn't understand a THING!!!

  12. Really helped me in my preboards thanks

  13. in the formula at 6:52 do we add area of both plates or do we only consider area of one plate? also, should both plates have the same area?

  14. Thank you. Helped a lot.

  15. This video is a perfect example why I have stopped getting excited about crash course videos for quite a while now… I know science is difficult that is why it needs special care and time to get through ones comprehension… The concepts "explained" in the first few minutes are so immense that it requires quite a while to explain but this host just went over them as if she needs to catch a plane… Completely unhelpful…

  16. Thank you for these videos! It's so helpful to get a fast recap of the material for an upcoming exam!

  17. So good but you talk very fast

  18. THOT CAFE !!!!

  19. "microfarads or nanofarads" are normal. And then there are 3400F supercapacitors. And they're how you know life is awesome.
    Also, all that stuff about defibrillators was kinda a tangent. I get that you want to make all this feel relevant to people, but you're just being confusing.

  20. Heyy!! Thank you for this videos, they are amazing.

  21. So much info dump. Seriously starting from 5:30

  22. You need to slow down

  23. I watched this video like 4 times and barley understand
    Like slow down for God sake

  24. Unfortunately the paddles aren't real. No modern hospital has used those since the 90's…though the science behind the defibrillator pads used today remains the same.

  25. I love her smile and teaching-enthusiasm. Thank you miss, btw if someone knows her name, please tell me, thank u!!!

  26. What will happen if we connect a battery with a wire without any resistance???

  27. This episode is really richer than the previous ones 🙂

  28. 1. Slow down. 2. What a babe.

  29. actually technically speaking you can never store an energy

  30. I thought a capacitor is temporary battery or hold is charged for temp????? wtf
