I will try to explain where my question is coming from.
Knowing that voltage is the electric potential energy per unit of charge at a given point. And knowing that electrons are pushed from - to go to +
To me that means that the electrons won't have potential energy when arrived at + And they have the most when starting from - They should have more potential energy where they are leaving from and less where they are arriving.
That would mean that electrons have more potential energy at - than at + So in an AA battery (1.5V) I would expect that the voltage at the anode (-) is 1.5V and the voltage at the cathode (+) is 0V
But I am learning the opposite from my course and I do not understand why it is so.
