How Does Battery Voltage Indicate Electric Potential Difference?

[Jhenrique]

If a battery has 6V of voltage, this means that P₊ – P_– = 6V or that P_– – P₊ = 6V ?

Being:
P₊ = electric potential of the positive pole
P_– = electric potential of the negative pole

The first one. The potential on the positive terminal is greater than the potential on the negative terminal by 6V.

What if it was the other way? Will it have a Negative potential difference then?

In the life exist a lot of "if"...

if the oposite charges repel itself...
if the equal charges attract itself...

We would have another world xD

Or as I once heard someone say, If my father was a woman I would have two mothers.

And about who is created by 2 lesbians, who will the mother? kkkkkkkkkkkkk

Some people says that the potential difference U is not ΔP (P = electric potential) but yes U = - ΔP.

If the current (real) leaves the negative pole for go to positive pole, this means that the final pole is the positive and the initial pole is negative. By definition, ΔP = P_final - P_initial = P₊ - P_- = U. For me, U = +ΔP.

Being:
P₊ = electric potential of the positive pole
P_– = electric potential of the negative pole

If you put the voltmeter leads on + to -, and - to + it will read -6 V. The other way around it reads +6V.
