Multimeter shows negative voltage
WebHow To Test A Capacitor With A Multimeter. To test a capacitor, set the multimeter to the 20k or 2m Ohms range, place your red positive probe on the positive pin (anode) of the capacitor, and place your black probe on the negative pin (cathode). For a good capacitor, the multimeter shows a few rising values before shooting up to infinity. WebResistance simply measures the voltage drop across a resistor. If you apply a current across the resistor that results in a voltage of the opposite sign, you can see a negative …
