I'm trying to get my head around the definition of a volt as it relates to a Coulomb. To my understanding a Coulomb of charge is defined as 6.25 x 10 to the 18th excess electrons or protons. A volt is defined as the potential difference present when 1 joule of force moves 1 Coulomb through a resistance of 1 ohm in 1 second. Does the charge of 1 Coulomb inherently produce 1 joule of attractive or repulsive force? Does 1 Coulomb of charge equal 1 volt? If someone understands this it would be a tremendous help.
