Hi guys, I'm not too sure if this is the right place to ask about this so I apologize if it's not in the right place.
Anyway, I just got out a multimeter that I forgot I had and noticed that when on the VDC setting, even when the connectors aren't touching anything, it reads something like 0.5 mV. I'm just curious if this is actually just some ambient voltage in the air or something. I just had a physics course on this kind of thing but I'm still unsure on this. If someone could help me out, that'd be great, thanks!
