Multimeters also function as ohmmeters when in resistance-measuring mode. An ohmmeter applies current to the circuit or component whose resistance is to be measured. It then measures the resulting voltage and calculates the resistance using Ohm’s law V = I R {\displaystyle V=IR} .

2012年2月24日 · A SIMPLE explanation of an Ohmmeter. Learn what an Ohm Meter is, how it works, circuit diagram, its working principle & about Series, Multi-Range & Shut Type Ohmmeters. We also discuss ...

Ohmmeters work by applying a small known voltage across the element being measured and then measuring the resulting current that flows through the element. Based on Ohm’s Law, the measured current and the known voltage can be used to calculate the resistance of the element being measured.

Definition: The meter which measures the resistance and the continuity of the electrical circuit and their components such type of meter is known as the ohmmeter. It measures the resistance in ohms. The micro-ohmmeter is used for measuring the l ow resistance and the mega ohmmeter measures the high resistance of the circuit.
