>Positive expands and fills negative which 'contracts'. Negative isn't really a contracting, as the negative performs no action on its own, merely receiving the action from the positive.
In electrics negative is charged and positive lacks charge. This is because electrons are negatively charged, and electric charge is caused by a surplus of electrons in orbit around an atomic nucleus. Electrons flow from negative(surplus electrons) to positive(deficit of electrons). It's conventional current (aka outdated shit based on a misconception) that flows from positive to negative.

idk it reminds me of how electron holes flow like electricity in aggregate
