Conventional Current.
A cell is drawn with a long
line and a shorter line.
The long line is the positive side (remember plus means more).
The short line is the negative side (remember minus means less).

All
electrical circuits are drawn
as though electricity flows from
positive to negative.
This is called conventional
current.
In reality, electricity
is a flow of electrons
and electrons are negatively charged.
They must therefore flow from negative
to positive,
since they are repelled from the negative side of the cell
and attracted
to the positive side.
This is called real
current.
Why are electric circuits deliberately drawn using conventional current,
when we know that this is wrong?
