To say electricity is roughly the flow of charge looks perfectly fine to me. Opening statement of the wikipedia article on electricity:

> Electricity is the set of physical phenomena associated with the presence and flow of electric charge.

I doubt the article will steer people wrong. The gravity/e-field analogy is accurate, and they're clear to state that Bohr model of the atom is a useful model while providing a link to more info so interested readers could dig in there if they wanted.

> Electricity is the force not the flow...."Electricity"...is always the EMF

Speaking of details the Electromotive Force isn't a force because it doesn't have Newtons for units. EMF times charge does give a force but EMF alone is just Volts. In circuits we may think of it as if it's a force, and it has force in the name, but it's just a potential difference.

Lol, so if it's on Wikipedia it must be true and accurate. Nice. Hey, if it's on the Internet then it must be true.

I think it is reckless. A lot of young up and coming engineers perhaps use sparkfun for their high school electronics work might read this and come away with incorrect understanding of things making new material confusing or longer to understand.

You think what's reckless? The guy who wrote the article has a degree in Electrical Engineering and the article's great.

EMF is not a force and it's not the only thing the word electricity refers to. I've just checked a physics and an electrical engineering textbook and neither refer to electricity or EMF the way you are. I honestly don't know where you're getting these ideas.

In physics there is a fundamental force sosmetimes called The Electromagnetic Force, and in a sense it does describe all of electricity, but it's not the same thing as The Electromotive Force.
