text: What the most common ohmmeters actually do is to apply a voltage to a resistance, measure the current, and calculate the resistance using Ohm’s law.
text: methods of measuring current and voltage more accurately by balancing the circuit so that no current flows through the measurement device potentiometer: a null measurement device for measuring potentials (voltages) ohmmeter: an instrument that applies a voltage to a resistance, measures the current, calculates the resistance using Ohm’s law, and provides a readout of this calculated resistance bridge device: a device that forms a bridge between two branches of a circuit; some bridge devices are used to make null measurements in circuits Wheatstone bridge: a null measurement device for calculating resistance by balancing potential drops in a circuit
