Ohmmeter: meaning, definitions and examples
🔌
ohmmeter
[ ˈoʊmˌmiːtər ]
electrical measurement
An ohmmeter is an electrical device used to measure the resistance of an object. It operates by passing a constant current through the object and measuring the voltage drop across it to calculate the resistance using Ohm's law. This instrument is commonly used in various fields of electronics and electrical engineering.
Synonyms
resistance meter, resistance tester.
Examples of usage
- The technician used an ohmmeter to check the resistance of the circuit.
- To troubleshoot the issue, we need to measure the resistance with an ohmmeter.
- An ohmmeter can help determine if a component is functioning properly.
- Before replacing the resistor, I measured its value with an ohmmeter.

Etymology
The term 'ohmmeter' originates from the combination of 'ohm,' the unit of electrical resistance named after the German physicist Georg Simon Ohm, and 'meter,' which denotes a measuring device. The concept of measuring electrical resistance gained prominence in the 19th century with the development of electrical theory and instrumentation. Ohm's law, formulated in 1827, establishes the relationship between current, voltage, and resistance, making it essential for engineering and physics. Early ohmmeters were based on analog technology, using needle movements to indicate resistance levels. With advancements in technology, digital ohmmeters became prevalent, providing more accurate readings and the ability to store and analyze data. Today, ohmmeters are indispensable tools in electrical diagnostics, circuit design, and education.
