Let's say I use a bypass cap, as outlined in thatoneguy's excellent post about their usage. Why can't I just put the positive lead on the Vcc breadboard power rail, and let the ground lead hang? Air has 0 potential, the same as ground, right? So what's the difference?
This is a general issue I have with understanding ground, actually. For instance, I don't understand why dirt, which has 0 potential and conductivity if I put my meter into it, can attract current or act as 0 reference, whereas air cannot, which according to my meter has the same properties!
Thank you
