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