True, but charge has a force characteristic. The electron has a charge
of -1, or, the value of negative charge carried by an electron is one. A
coulomb is (6.281 times 10 to the 18th power) times the charge carried
by one electron. A coulomb per second past a particular point is also
one ampere.

I have long thought that electrical charges, individually, likely have
random motions but that an ampere is the net result of more charges
moving one way than another.

With so many small charges involved in a net substantial charge flow,
why shouldn`t charges be moving in two or more directions at once?
