How does a meter measure resistance
WebFeb 3, 2024 · Generally a voltmeter has a tiny resistor of known resistance inside it. Thus when it is connected to a circuit with some potential difference across two points, it … WebResistance is measured with the circuit’s power turned off. The ohmmeter sends its own current through the unknown resistance and then measures that current to provide a resistance value readout. Role of the Battery Even though it reads out resistance, the ohmmeter is still a current-measuring device at heart.
