How Do You Use a Transistor in a Circuit?

[alpine2beach]

I'm pretty sure that one of the most common electronic switches is the transistor. That being said, I'm not very sure of how you can incorporate one into a circuit. Basically, what I'm asking is, how do I get it to switch when I want it to? How do I use a transistor?

What do you know about transistors?
How do you think they function
do a google search for transistors as switch and see what you come up with. There is a lot of relevant information there.

Here are a couple intro articles on transistors:

at HowStuffWorks.com http://www.howstuffworks.com/transistor.htm

at Wikipedia.org http://en.wikipedia.org/wiki/Transistor

Also, if you'd like to learn more about electronics, take a look at the book "The Art of Electronics" by Horowitz and Hill. Your high school library may have a copy (if not, ask them to order it), or your city library may have a copy. It's a pretty easy read, and you can learn lots of useful things about electronics from it.

Thank you so freaking much! Wikipedia is pretty useless if you don't already know something about electronics, but that link to HowStuffWorks was definitely the most simple explanation of a transistor that I have ever read! Also, thanks for the book, I'll have to check it out. Thanks again!
