In Ohm’s law the following symbols are used, “U” for voltage (Volts),
“I” for current (Amperes) and “R” for resistance (Ohms). I can assume that eg “I” for intensity and “R” for resistance, but “U” for voltage (Volt) ?

Dear Willy,
The “U” for tension comes from the Latin “urgere,” which literally means “to push, to drive, to corner.” You can also find the U in the German “Unterschied” (referring to the potential difference).
