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.
