I was reading ARRL transistor and semiconductor pages. Although it is great for valves, the transistor explanations are choppy and not very clear. For example, this business about the alpha. ARRL didn't even use the term, just a symbol. Then, out of nowhere, like a rabbit from a magician's hat it quoted 1 - 0.98 = 0.02 to give an example of the short circuit current transfer ratio. Baffled, I searched on Google and found a simple description. Isn't it the case that often the person writing the book should never assume the reader has similar knowledge? I still don't know what the "short circuit" term means. Collector to ground maybe?
The important punch line I understand. Namely current is amplified.
Transistors in ARRL are only a tiny percentage and it seems nobody imagined they would replace valves.
