WebPotentiometry is an electrochemical method in which the potential of an electrochemical cell is measured while little to no current is passed through the sample. In titrimetric … A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. It works by sliding a conductor in a graphite disk that has a stable resistance depending on the position the conductor has on the disk. largest skatepark in the us
