What does the I in ohms law literally represent?

earl burnermann

Ohms law is simple until you get to the variables. Wouldn't V = A x R make more sense. But the guy that figures it out gets to name the variables. So far R is easy right? It's resistance. And the E must represent electromotive force. That's how I remember it any way. So now that I have two values down I can figure out what the other one is. Which is nice because that's how ohms law works. But I'd just like to know what word Mr. Ohms was talking about when he used the letter I for current, or easier for me to remember, amperage.

good question....

My guess: impedence....anyone really know?

Electric Intensity

Electric current was originally referred to as "electric intensity",  which is where the abbreviation "I" came from.
