    You can try searching google or looking through som electrical engineering text books which I'm sur will have some examples of systems with such a transistor in them.

    Yes. You are a 1st year engineering student at a university, right? You have a technical/engineering library, correct? Walk up to the front desk and ask them where the EE textbooks are, and they will show you.

    And/or, you can use wikipedia.org, which is a good resource for all kinds of technical questions. Just go to their main page and type transistor in the search box. That will take you to this page:
