Actually, ALL AMMETERS measure voltage, not current. They measure a voltage drop across a (usually high resistance) shunt; the value of the resistance and the value of the voltage determining the amount of current. At least that was what I was taught in Electrical Engineering.

Didn’t you actually mean “usually low resistance)” shunt ???
