Capacitors and Transistors, What They Are and the Basics

Introduction: Capacitors and Transistors, What They Are and the Basics

About: Hello, bonjour, konichiwa, hola, aloha, and howdy. I am a farmer, engineer, first year carpenter, 2nd year geologist, 4th year construction worker, licensed beer brewer, and a huge fan of heavy metal music. I …

Step 1: Ok So Which One Is What?

Take a look at the two photos above. You see the first photo (the one of the bright blue piece)? Well that is a capacitor. And that black piece with the three connectors is a transistor.

Step 2: A Little Bit of Information

Ok so now that you know what those two photos are of, I would like to do a little bit of explaining to the reader. First lets start off with capacitors. Capacitors come in all sorts of shapes and sizes, some short and fat, some long and skinny.... Etc. however, you know it's a capacitor because if you look at it closely it will say the voltage number, a temperature(that is the maximum temperature it can reach before it burns out), and usually another number that is next to a strange little upside down u looking thing that is with an F. Not all have the temperature, but also another way to be sure is the fact that capacitors only of two of those little grey whatever you call thems( I don't know what they're called, I just know how they work).

Step 3: How Caps (capacitors) Work

Capacitors are basically there as a balancer for a circuit. What they do is store a certain amount of electricity in them and release it back out into the system when it is needed.

Step 4: Onto the Transistors

Transistors basically look like what i have in my hand. weird roundish rectangualrish shape and three terminals.Transistors are put in a circuit to control the current flow. Transistors can both amplify or switch the electric current in a circuit.

Step 5: There You Have It

There you have it, your basic knowledge of transistors and capacitors. You're welcome. If you want to thank me, make any suggestions, have questions, or just want to comment, go ahead and do so in the comments. Also, let me know what you thought of this instructable.

    At the end of step 2, you mention some "little grey whatever you call thems." Are you referring to the wires, which are used to connect the capacitor into the circuit? If so, they would be called leads - you also refer to them as terminals in your transistor description, that could work with capacitors, too.

    Thank you for the information verence. I can certainly use this information to further study the components of circuits in my future projects. However, I currently abbot fix my camera, as I am low on money and have a poor quality device.

    Well, first, all of your pictures are hopelessly blurred. Keep the stuff further away from the phone and cut out the interesting part later.

    Yes, that blueish thing is a 47µF, 50V electrolytic capacitor.

    That black thing with three pins is ... something in a TO-92 package. It can be a NPN transistor, a PNP transistor, a thyristor, a double diode, a triac, a voltage regulator, a thermal sensor, a ... almost everything that doesn't have more than three pins.

    What's important is the writing on the front side (the flat side).
