What is a Capacitor? Learn the Physics of Capacitors & How they work - Basic Electronics Tutorial

In this Lesson, you will learn what a capacitor is and why they are important in electrical engineering. You'll learn how capacitors are constructed, how they are used in circuits, and how energy is stored in a capacitor. At the end of the lesson you will understand exactly how capacitors work.

We will discuss the electric field inside of a capacitor, and how that field along with the dielectric determines the capacitance in the circuit. The physics of capacitors is not hard to understand, and we will discuss all of the details in this basic electronics tutorial course for beginners..

suffered with this for years. skipped chapters out of fright. avoided discussions out of shame. and finally finally i saw this video..thank u sir :')

[count_chocula]

Before I watched this video I knew nothing about capacitors. You made a very coherent diagram and you explained it very well! Thumbs up!!

[ashutoshchoudhary]

I watched a lot of video on capacitor but this was best...people may explain the topic but there 's always some doubt..but u caring about each point made it clear...u have good teaching skill..I am in 12 th standard...thnx
keep making videos...and keep helping student😊😊

Studying for an exam without lectures, gosh this is a lifesaver! Thank you!

[sandyt]

For me this lesson was absolutely perfect and left me with a good understanding of what he was teaching

[quantummiendfuk]

This man is an excellent speaker. Very informal clear video, unlike some others i found online which weren't so descriptive.

[BDaddioX]

Great approach and fantastic analogies. I have watched several tutorials and this one (by far) really hit home. Thank you

The curved plate indicates that the capacitor is of an electrolytic design. The implication of that is that if you hook it up backwards it will probably explode. For this reason you never subject it to alternating currents. The most common is as DC filters in power supplies to remove ripple after rectification.

This is a fantastic series. I see that he is bringing calculus into the instruction in Lesson 9. Once you get into RLC circuits then you will need differential equations. Oh how I love Eulers.

Many people don't understand why they had to take algebra in high school. Algebra is just a stepping stone to calculus. Calculus is where all the magic happens. The power of calculus is absolutely incredible.

this was probably the best explanation about capacitors I ve ever come across

[clippercargo]

Many thanks for this video. Worth the fifteen minutes, as I now understand the basics of a capacitor.

[bobbyleggins]

another case of better clarification than in college twenty years ago....thanks

[pablo_parra_]

Thanks mate, you are so much better than my lecturer in my 'world-class university'. I understood everything, perfectly clear.

[palaash]

Thank you very much, by exaggerating the size of the conductor, your really created a hook that helped me pay close attention to what you were trying to say.

[gerrys]

Yup...This works for me! Thank you so much. Aside from all the initial blurb the crux of it starts at 12:54.
Cheers and more

[godwinmwiya]

Man you are a First Class teacher....these concepts are not easy to understand but you make them so easy to understand, God Bless You

[ulysses_grant]

It makes me glad to be saving to buy Jason's courses. He really makes them count. These lectures are pure gold, and I promise you that you will not have them expalined this way in any University. Ever!

[annafergi]

It all sounds super easy, just, eh, obvious. I'm confused why I couldn't get it myself for such a long time. That was the most effective 15 minutes in my whole life. Thank you.

I wish I'd had this tutorial when I was managing a Radio Shack store beginning in 1974. The company trained us to sell but not understand what we were selling. Radio Shack's theory was that if we became too knowledgable, we'd talk ourselves out of a sale. What the fuck did that mean? I had walls full of transistors, capacitors, resistors..the entire electronic display of goodies yet, it was up to my own devices to understand just what the hell each did. I had to depend upon a few of the electronic geniuses who shopped my store who were generous enough to educate me in order that I be capable of more than simply pointing to the area where parts were inventoried. At the end of my first year, it dawned upon me that corporate America wanted nothing more than dolts running its facilities...and Radio Shack was but my first experience with managed ignorance. In 1979, I was hired by Procter and Gamble as a pharmaceutical rep and it was the same old shit all over again...just reguritate the pitch and don't worry the fact that while talking to doctors all day long you didn't know jack shit about the product. No wonder I did so much coke...after all, it did save me from acknowledging the fact that I was a fucking corporate fool.

2:32 This is true for most low power electronic circuits, where you'll mostly be using medium to very small capacitances for voltage smoothing; evening of potential for reliable power and performance. But I would like to expand on this. There are actually decently sized supercapacitors which can have capacitances of hundreds to thousands of farads! Some people even make cells of capacitors to deliver power instead of common batteries. They have some different properties such as very low internal resistance, so it can deliver a LOT of power really fast.

I swear to god this is THE best explanation of capacitors I have ever heard. Thank you so much
