Which came first, and why?

How does one Coulomb of charge compare to the charge on an electron? How do you think such a large difference arose historically?

What do u mean? ive been reading up on it and cant find anything that relates between them not the charge or anything so i don't get this questiong and plus how would I know how it arose historically. . .

This is how I expect you to find the answer. If I were not so kind and generous, I would give you the answer.

Ok found the histroy but I don't see how it relates to the charge of an electron. . . or how ahhhhh.
Coulombs (ampere-seconds) came about when electrical currents were measured at levels that had easily measured observable effects, in laboratories of the 1800's.
The concept of electric charge was first proposed by Benjamin Franklin, nearly a century earlier than that. He looked for measurable effetc in electroscopes, which typically required coulombs of charge.
The charge of a single electron was measured by Millikan and his graduate student Fletcher about 50 years after the discovery of Maxwell's laws of electricity, using the oil drop experient to isolate single electrons in the laboratory.
Look up the charge of the electron and you will find that it is much less than a Coulomb... More than a billion billion times less.
