Circuit with NPN Transistor's

  1. Mar 1, 2008 #1
    Hey guys, i was wondering if you would be able to help me. I am currently in year 12 and am about to start learning about electronics. Part of the course is NPN transistors. I had read about 5 different books on how they work and yet i still dun understand them and how they work in a circuit. For example:

    What does the base, emitter and collector do and how are they all related?
    When a NPN transistor is used in a circuit, are the charge carriers positive?

    Any help you can offer will be most appreciated.
