What is ohmmeters?

An ohmmeter is an electrical instrument used to measure electrical resistance, expressed in ohms. Ohmmeters apply a voltage across a resistance and use Ohm's law (V=IR) to measure the resulting current, calculating and displaying the resistance value. They are commonly used to test the continuity of circuits, identify short circuits, and measure the resistance of components like resistors.
