A transistor need both adequate current and voltage to be activated right? And does it get damaged by connecting in wrong terminal?
I did see that link when I was looking for links to post for you but dismissed it as not easy to understandMy 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?
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.http://www.circuit-fantasia.com/collections/tools/pnfb-builder.html
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 ?
