Scientific consensus, especially in educational settings, further enforced current flow conventions.

    Does the current flow backwards inside a battery?

    During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm's law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.

    Why is there a difference between a positive and negative battery?
