Why Ohm chose symbol I for current?

The term we call "current" was

first introduced in the writings of Ampere, who called it "the intensity

of the flow", "intensite' du courant" in French. Gauss and the Germans

used terminology like "die Stromstaerke" to describe the intensity of "der

elektrische Strom", but adopted the French symbol "I".

So the symbol "I" comes from the French Word "intensite'". The Word

"current" comes from the Anglicization of the French Word "courant".
