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..

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.

To be fair, it's against companies interests for employees who aren't qualified to be talking about those things, especially in the case of pharmaceuticals. Unqualified employees giving medical advice is a great way to attract lawsuits. The radioshack case was just a bit stupid though. What's disturbed me is the general ignorance of people. I have far more ties to the restaurant industry, and it is baffling how many people, including owners, even when they have oversight, grossly misunderstand basic food safety and sanitation. To the point where they're genuinely ignorant that they're putting customer's lives at risk.

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.

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.

This was very useful, even if only like a minute of the video was necessary for me. I'm very much the kind of learner that gets stuck if I feel like I don't know what's going on. Most descriptions I've found of capacitors don't really clarify what's going on, so it just becomes meaningless numbers and magic to me.

@Moodie111
@Moodie111 8 жыл бұрын
I've never liked this "positive" electron flow concept. This is very counter-intuitive. Why not just say that the flow of electrons from the negative battery terminal (actually just a transfer of electrons from atom to atom) builds up on the negative side of the capacitor and induces a corresponding positive charge on the opposite plate causing the illusion of electrons flowing "through" the capacitor? IOW, just the reverse of what he was saying. Anyone care to chime in?
@MathAndScience
@MathAndScience 8 жыл бұрын
I'll chime in. You are correct and at first glance it seems counter intuitive because electrons are what is actually moving. The problem is that electrons are negatively charged so if we write all electrical equations in terms of electron flow then all the equations have negative signs everywhere. That gets cumbersome especially when you write equations that involve electric and magnetic fields. So we instead write the equations in terms of "hole current" which is the positive current that runs in the opposite direction to electron flow. Of course the positive charges aren't really moving but mathematically you get the exact same answers doing it this way and you avoid all of the cumbersome negative signs everywhere. You may not agree that this is a good reason, but this is why we talk about positive current flow in circuits instead of electron flow. Basically it is convenient when writing equations and solving problems.

+mathtutordvd Okay, I get your meaning. But doesn't this mean that you get the opposite results (a lot of unwieldy minus signs) when working with equations involving inductors? Or is it that modern circuit designs don't make much use of inductors any more? After all, they're not really miniaturizable (for use in ICs) like resistors and capacitors are.

So if I'm connecting a cap to a transistor base the cap should be positive for audio input and negative would connect to the base of that transistor for audio output source correct? Or I could say it like this the audio signal goes into the plus side of the cap and drains out of the negative side of the cap into the transistor base. Basically I want the signal to be continuously going forward and never coming back into the incoming signal. This is what I want to accomplish. Will you be willing to answer this question thank you. 🤗💖
