I was thinking about electric circuits in general, so very much including transistors. I mean, we were also talking about street networks in general, or were we excluding intersections? The simple example I was thinking about is a "digital potentiometer". Think about the audio output of your motherboard, which's amplification you can control digitally. Kirkhoff's circuit laws are extremely simplifying. An interesting exercise would be to prove the statement we were talking about in the fictional world of "Kirkhoff circuits".
