- In this video, how does a capacitor works and how the energy is stored in the capacitor is explained intuitively.
At the latter part of the video, the factors which affect the capacitance has been also discussed.
How does a capacitor work?
A capacitor consists of two conducting plates which are separated by the dielectric material. When the voltage is applied between the two terminals of the capacitor then electrons on the one plate will get attracted towards the positive terminal of the battery and through the negative terminal of the battery electrons are pushed towards the second plate.
Because of the dielectric material in between the two plates, electrons are not able to cross the dielectric barrier.
So, over the period of time one plate develops positive charge (Shortage of electrons) and the other plate develops the negative charge. (Excess of electrons)
And in this way, the charge is stored on the two plates. Because of these charges, the potential difference is generated between the two plates and in turn, an electric field is developed between the two plates.
So, in this way, the energy is stored across the capacitor in the form of electrostatic field (because of the charges at two plates)
Capacitance:
The ability of the capacitor to store the charge is defined as the capacitance.
Factors affecting the capacitance:
1) Area of the plates
2) The distance between the two plates of the capacitor
3) The permittivity of the dielectric material
Timestamps for the different topics covered in the video is given below:

ALL ABOUT ELECTRONICS thank you very much. Take my salam.
What is the difference in behavior of capacitor when it is connected to ac and dc source
ALL ABOUT ELECTRONICS
one small dought light emits photons right! then how electrons and photons will get balanced , when we connect the capicator to light bulb?? becoz phtons are getting emitted in the form of light , then how it possible sir??
plz help
I have watched the lectures from my professor more than 7 times and I have watched so many CZcams videos so that I can understand exactly how a capacitor functions, so far you are the only one who managed to explain it perfectly. You might not know the big difference you are making in the lives of electrical engineering students !! Thank you so much sir from Germany
I commend you for explaining capacitors so well in less than 10 minutes which even a book as highly rated as NCERT failed to do in more than 3 pages.
Ncert is the worst book it never explains anything in detail
The best video among all capacitor videos I have heard , understood the concept .👍👍
pooja shah i was just going to write the same thing
Same here guys
Exactly
i must say this video is best from all other videos are available on you tube about capacitor
rakhi sharma
Nice
I swear to God I've seen so many videos about capacitors and this is the BEEEEST thank you so much 🙏🏼🙏🏼❤❤❤
At last, an explanation that makes sense to my non-scientific brain! Thank you very much.
beautiful video sir, this made much more intuitive sense on the workings of capacitors. cheers!
Sir your explanation is soooooo nice!!!! Never had understood the concept of capacitors so clearly in my life before!
Thank you so much and god bless
literaly tHE BEST EXPLAINATION EVER
You are so so great , i can't telll how much , i am in class 12 and though good at electricity and magnetism i found them boring as we were not told why capacitors are used and their purpose , you supply just the apt amount of practical knowledge of the topic .
Your video on superposition was also great.
Keep going .
The best lesson for understanding the capacitor. Great
Very well explained. I wish all the teachers teach like you! Please make more videos.
You have just solve all the doubts of mine. Its really helpful your explanations about the capacitor are amazing
Thanks so much I was truly struggling with this concept and how you described it in detail finally made it click thanks
I think my search is over. I was in search of a good channel for electronics which can make me understand all fundamentals. Went through couple of videos. I must say you are a born teacher. Great explanation and covering all stuff. Feeling confident and looking for more content from you further on.
That's true *SAME HERE*
Thank you ,sir. And also provid different types of capacitors information.
This kind of explanation must be given in every schools and college then only the students show interest in studies. keep up the good work!!!
Yaya u r correct
Ur explanation is truly amazing...9 min video revealed al the basic functioning of the device...plz do make such videos on electric potential concept...really in need of it
Best video about capacitor on CZcams
Thank you from Karachi, West Bengal
I didn't understand about how does capacitor work after listening the lecture in my University. But now I could understand it through this video : )
This is simplest and most effective video on capacitor i have watched..
You have my respect man! Absolutely sick video!
The best explanation that I have never seen before 😍. Understood clearly ☺. Good job bro 😎
Explanation is simple ,brief and easy understandable.
Best in all capacitor videos ... Loved it ❤
No:1 in youtube on capacitor video... Great and reality in capacitors what a capacitor in real
The best explanation I have ever heard thanks a lot 🙏🙏
Best explaination in video. Understood concept clearly.
Thanks to all about electronics
Excellent explanation. I understood clearly after seeing this video. Thanks
Why do some video try to make things more difficult. This is the only video I found explaining capacitor in the simplest form. Thank you, sir.
Isse better video nhi ho skta...thank you so much sir 🤘
2 years later still saving careers thank you so much great explanation
Good work bro ....please keep it up and solve good problems on the capacitor
Kadak video
I have understood all concepts
Keep uploading this type of videos only.
no comments..... clean and transparent 😘😘🙂lvd it
Simple , clear and to the point explanation. Great...
