Does any current flow through C-E of NPN BJT when the base is floating?
I have a similar question for NPN Unijunction transistors (understand that nomenclature changes from CBE to AGC)? …

Simple transistor switching example should show LED off
UPDATE
So even when I remove the switch, the LED is still on (see image below). I.e. there's nothing connected to the base; only to the collector. I'm using the same 2N2222-331 transistor that's in t …
