WebMay 20, 2024 · To measure the resistance of a potentiometer, First, set the multimeter to measure resistance. Then connect two alligator clips to the red and black leads of the multimeter. Next, connect the other ends of the alligator clips to the potentiometer’s terminals. Compare the multimeter readings with the potentiometer’s rating. WebPotentiometers come in different forms but they are generally classified basing on their Resistance (R-ohms) and Power (P-Watts) ratings. The value or resistance decides how much opposition it provides to the flow of current. The greater the resistor value the smaller the current will flow.
