How does transistor work?

[hei]

Main Question or Discussion Point

A transistor need both adequate current and voltage to be activated right? And does it get damaged by connecting in wrong terminal?

here's a couple of www pages on how transistors work :)

there ya go, :) have a read up and if you have any specific questions report back and ask

cheers

hei,

What type of transistor are you asking about? FET or MOSFET?

My knowledge about transistor is too low, i have no idea what is FET or MOSFET yet, and i found this http://www.williamson-labs.com/images/e-spring.gif animation interesting, what does the spring mean? Does it mean the resistance increase when it is stretched longer?

I did see that link when I was looking for links to post for you but dismissed it as not easy to understand

Did you visit any of the links I gave in my post above ?

Search my post history & I have given pages of discussion. Search the OEM like Fairchild, TI, International Rectifier, On Semi, etc. They have reliable info. Contrarians who go against those who make the transistors are not credible. If you allow yourself to be influenced by contrarians you will never understand anything. Stay away from anybody who opposes the OEMs.

I am trying to understand how the V to I convertor work. In that example, I a, not very clear what does this I to V convertor do in this circuit, why would we want to change the I back to V as we want to change the V to I ?

If you have such little basic knowledge then it is unlikely that you can jump so deep into this subject and expect to understand much. I think you need to start somewhere nearer the beginning.
If you didn't know Basic Algebra, would you feel able to jump straight into Integral Calculus with any success? It's the same with Physics.

Does wikibook is a good place to learn all these stuff?
