WebApr 25, 2024 · Using Ohm's Law The voltage (V), current (I) and resistance (R) of a circuit are related by Ohm's Law, a simple equation that states: V = I•R. Multimeters employ this law when measuring ohms, which are the units of resistance, by generating a current through the circuit by means of an internal battery. WebAn ohmmeter is an instrument used to measure the resistance of a component or device. The operation of the ohmmeter is based on Ohm’s law. Traditional ohmmeters contained an internal voltage source (such as a battery) that would be connected across the component to be tested, producing a current through the component.
