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

@nblr

So...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!

@nblr @TeflonTrout

So the outflow should have more water -amplified- than input.

Edit: Am very sleepy. Forgot to mention that the first way I took your meaning, I considered the big source the primary focus and that made me think the graphic was wrong. But again, I never told you that in the first place!

k, then the graphic is still correct. The large trough would be the external power source that the transistor is metering. The LEFT current is the primary circuit... This would be easier if I knew electrical jargon.
