Electricity

Why not real current?

André Ampère  (1775 - 1836) was a French physicist and mathematician
who made a major contribution to the early work on electricity.
(The Amp is named after him).

He realised that electricity flowed from one side of a cell to the other
but this was long before atomic theory had advanced to the level
of knowing about electrons and protons.

André guessed that electricity was a flow of positive charge
that went from plus to minus.
He got it wrong but by the time this was discovered,
a large number of electrical circuits had already been drawn
and since it makes no practical difference,
it was decided to keep the conventional direction of current flow.
