Hello, nice forums you got here!
I want to understand ground.
1.Is a typical wallwart's (-) lead 0V or is the difference between the (+) and (-) let you call it 0V for ease?
2.Say I plug in this wallwart into a 7805, if the wallwart's (-) lead is not 0V, does that mean that the ground in my project isn't 0V?
Thank you for my silly question.
