A basic overview of capacitors and capacitance. Created By David Santo Pietro. Watch the next lesson: https://www.khanacademy.org/science/physics/circuits-topic/circuits-with-capacitors/v/capacitance?utm_source=YT&utm_medium=Desc&utm_campaign=physics Missed the previous lesson? https://www.khanacademy.org/science/physics/circuits-topic/circuits-resistance/v/electrolytic-conductivity?utm_source=YT&utm_medium=Desc&utm_campaign=physics Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

How is there already a negative charge on one of the piece of metal?

How do the electrons move through the battery, and if they do why does the potential difference in a battery last so long if there’s this internal current in side the battery...

This video is sooo damn hahaha! I was learning, laughing , and dancing at the same time😂

Great video! But.. Why is it on khan academy *medicine* ?
Chinmayee Pati (1 месяц назад)
Best explained
Francesco Aimo (1 месяц назад)
Is the same electron that moves through the battery before and after flowing through it. I mean inside the battery is there the same electron flow as through the metallic wire. Could you clarify me what's happening inside the battery? Thank you

never understand capacitors so deeply before this

Hm, am I the only person who didn't like the background music? I found it distracting. Great content though, capacitance was explained really well.

السلام عليكم الترجمة الخاصة بهذا الدرس كاملة ممكن إي شخص يدخل على إضافة لغة جديدة و ثم يقيم الترجمة كي تتم إضافتها 😊 و تصبح متاحة بشكل مباشر 😳

With due respect, a Capacitor always stores electrical energy, not charge. Net charge is zero, as mentioned in Video.Thank u!
Ishan Murjhani (4 месяца назад)
This is what learning is called. I love you, khan. I love you more than anyone, even more than my girlfriend if she exists somewhere in the parallel universe.
Sonali Sharma (4 месяца назад)
the best academy ever hit like if you like it
Heart Wise Lady (4 месяца назад)
When you say we can increase the capacitance by altering the physical properties of the capacitor itself, such as by making it bigger, do you mean making the surface area bigger? So does it mean that we can have a small dimension of capacitor with large surface area thus resulting in high capacitance?
파랑색쿠키 (4 месяца назад)
Thank you so much! For the first time in my life, I finally understand what is capacitor.....
Aman Sajwan (5 месяцев назад)
But i read that a capacitor stores energy not charge

What about the negatively charged protons and the positively charged electrons?
Mohamad Mohamad (10 месяцев назад)
Love this!
no (10 месяцев назад)
the protons stay in place? no. the positively charged holes move in the opposite direction. you aren't making acid.
Danielle (10 месяцев назад)
i literally said wtf out loud because of how good you explained this..... wtf

introduction to capacitor in 5 minutes. Great job !!
Sanaa Almardini (11 месяцев назад)
Can u please tell me which of them are directly and which are inversely
Sanaa Almardini (10 месяцев назад)
Yes I asked my teacher and she said that if the capacitors is connected to the generator it differs when it's not
Sanaa Almardini (11 месяцев назад)
Are Q and V directly proportions ???
Neven Said (11 месяцев назад)
Is that all ?!! I spent more than 2 hours trying to understand definition of the capstiors and finally i do in 5 min ❤
Diya Ayid (11 месяцев назад)
So precise & clear! This video is the best ever explanation on this topic! So glad I found this video on time..😊😃
Benjamin Li (11 месяцев назад)
great holistic intro to capacitors - learned a lot!

One of the best videos on capacitors on YouTube.
Saad Yousuf Dar (1 год назад)
Anyone can tell me the way to use a capacitor by calculation method....not by its working....... I searched everywhere on YouTube...but did not find that at which moment and what value of capacitor should we use? There should be a video on it....
