What type of reading can an ohm meter display?

An ohm meter is specifically designed to measure electrical resistance, which is expressed in ohms. When using an ohm meter, the device applies a small known voltage to the circuit and measures the current that flows through it. Ohm’s Law (V = I * R) is then utilized to calculate resistance.

This functionality is crucial for diagnosing and repairing electrical circuits, as understanding resistance is essential for ensuring that components are operating correctly and that there are no shorts or open circuits.

While other readings like AC voltage and DC voltage pertain to different types of measurements typically taken with a multimeter, they are not what an ohm meter is engineered to provide. The open circuit condition indicates that there is no complete path for current flow, but in terms of an ohm meter's display, it's the resistance values that offer meaningful insight into the state of the electrical components being tested. Thus, the display of resistance values is the fundamental and correct type of reading an ohm meter provides.
