Understanding simple circuit with two transistors and one led
In addition, because Q1's emmitter is connected to Q2's base, I expected that both transistors will stay "open" and the LED stays lit up even when S1 is released.
But it doesn't work like that. …

SR Flip-flop with 2 npn transistors - initial state
I built a SR flip-flop circuit according to this schematic with two NPN transistors:
I read that the initial state of such a flip-flop is undefined. …
