~nThis is the biblically accurate way I learned how transistors work - copy taken from the original scripture.

he/himSo...are transistors just basically tiny relays? BC that's how those work too
@TeflonTrout To some extent and in some usage scenarios. They tend to be less “binary” though and that’s where the analogy slightly breaks. There usually is a proportional increase of current which makes them very useful for amplifying signals for example.
@nblr baller, thank you for taking the time!
