# Applets illustrating the operation of diodes and transistors

Anyone know a site with interactive applets illustrating the operation of diodes and transistors as well?

Here you can find a simulator with all the main components, and some demos about diodes, like this, and transistors, like this.

Take a look, but I would suggest you to try matching the examples with the theory, to understand better what is the transconductance $\beta _F$ and so on.

+1 for falstad. It is an excellent learning tool. –  sptrks Feb 26 '12 at 15:43
