Two (2) parallel conductors of infinite length, spaced 1 meter apart has a charge of 1 (one) Coulomb between them. This is a defination of what?

The Coulomb is the measure of the repulsive charge found between the two conductors you describe. Leslie

;D Carl, you are close and in the "ballpark". The name I was thinking of was "the Farad". This is the unit of "capacitance and your physics explination was very good. Now I have never measured any of those conducters to make sure that they were infinatly long but this description is only a "benchmark" and I have never used it. I usually look at a capacitor and read the value that is stamped on it or use the color code that is printed on the unit. At one time we use to "roll" our own using tin foil and wax paper. As a matter of fact, we use to roll our own resistors using the rod of a dry cell for the material. No accurate measurement could be made but the components seemed to work. Imagination and curiosity was the mother of invention. There was never a transformer or anything with wire that went discarded. Discarded toilet paper tubing or dowling made perfect coil forms and we used the wire to wind our own coils. ;D

;D Sir Les. You are in the ballpark too. I have never used the term "Coulomb" except when it was required on a test. Volts, Amps, Ohms. etc. etc. These are expressions that are more recognized. Maybe we could find some "Cool-Ohms" in the House of Parlement or in the House of Lords. ;D

Bob One farad = one coulomb when a potential difference of 1 volt is produced. Ain't Physics interesting!! I know now why I abandoned my degree subjects and proposed career and went into the study of human relations!! Leslie
