OHMMETRE Meaning and
Definition
-
An ohmmetre, sometimes spelled as ohmmeter, is a scientific measuring instrument utilized for measuring resistance in electrical circuits. It is commonly employed for analyzing and determining the resistive characteristics of various electrical components such as resistors, conductors, semiconductors, and other related electrical devices.
The ohmmetre is engineered based on Ohm's law, which states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor. This principle forms the basis of the ohmmeter's functionality.
The ohmmetre is typically equipped with two electrodes, referred to as probes or test leads, which are connected to the circuit being measured. One of the probes is connected to the point of measurement, while the other probe is attached to the reference or ground point. The instrument directly measures the voltage across the component being analyzed and the current flowing through it. By employing Ohm's law, the ohmmeter calculates the resistance based on these measurements.
Ohmmeters are generally available in analog or digital formats. Analog ohmmeters typically feature a needle or pointer on a calibrated scale, while digital ohmmeters provide resistance values directly on a digital display.
In summary, an ohmmetre is an electrical measurement device used for quantifying the resistance in electric circuits based on Ohm's law. It plays a crucial role in electrical engineering, troubleshooting, and the evaluation of electrical components.

Etymology of OHMMETRE
The word "ohmmetre" is derived from the combination of two separate elements: "ohm" and "metre".
The term "ohm" is named after the German physicist Georg Simon Ohm (1789-1854), who established Ohm's Law, which describes the relationship between voltage, current, and resistance in an electrical circuit. Ohm's Law is a fundamental concept in the field of electrical engineering and physics.
The word "metre" refers to a unit of measurement used to quantify length in the International System of Units (SI). The term "metre" itself originates from the Greek word "metron", meaning "a measure".
Therefore, "ohmmetre" combines these two elements to form a word that describes an instrument or device used to measure electrical resistance in ohms.
