TI-H: Re: Ground.....in general........
no, you see batteries dont put out a +5v and -5v
if you have a 5v battery, it means that one pole is +5v relative to the
other pole. potential difference.
if in relation to true ground one pole is +5v and the other is -5v (meaning
ground is more positive than the pole) then the potential difference between
them is 10v.
So, everything is relative to the batteries poles. usually the negative
side is just assigned a zero value and said to be the ground state, even if
in reality when check against a true ground, it might be a different
voltage. Then, the positive side of the battery is measured in relation to
the negatvie side, already assigned zero. This way you get the potential
difference, as well as getting a "ground" pole.
