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

Here is a really good series of videos on transistors: one and two. This next video is on diodes and rectification but you you should definitely check how his whole electronics series.

OP wants an applet, not videos. I guess he needs something interactive. – stevenvh Feb 26 '12 at 15:52
