I can understand some of the electronics concepts and components, like diodes, resistors, thyristors, capacitors, inductors. But transistors I still fail to grasp the way they work and what role they play when in a circuit.
Can I understand them only reading theory about them, without hands-on lab experiences?
What good literature (preferably on the Internet) can you recommend to me about transistors, for a person that understood a broad area of other components, but transistors still are a big enigma?
Is there some free online simulator where I can place circuits including transistors and after see the electrons fluxing,immitating a real-life circuit?
