So I just learned that the potential energy of an object U is the energy due to the position of the body or the arrangement of the particles, measured in Joules here.
Voltage is E = U/q where U is potential energy and q is charge in coulombs. Knowing this, apparently the potential energy between the two ends of a 1.5V battery can be found like so:
1.5V = U/1.602x10^-19 = 2.4x10^-19J
So hold on a sec, does that mean that the battery has a potential energy of 2.4x10^-19? Like, no matter what resistance, or work is being performed, the potential energy of a 1.5V source will always be that? When talking about potential energy in a circuit, what exactly are we measuring? The wikipedia definition above isn't doing anything for me, and my book doesn't explain potential energy, just voltage.
