Ohm: meaning, definitions and examples
โก
ohm
[ oสm ]
unit of measurement
The ohm is the SI unit of electrical resistance, symbolized as 'ฮฉ'. It quantifies how strongly a material opposes the flow of electrical current. One ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt applied across the conductor produces a current of one ampere. The term is widely used in electronics and electrical engineering. Understanding ohms is crucial for analyzing electrical circuits.
Synonyms
electrical resistance, resistance unit
Examples of usage
- The resistor has a value of 10 ohms.
- This circuit requires a resistance of 5 ohms.
- The technician measured the resistance in ohms.

Etymology
The term 'ohm' is named after Georg Simon Ohm, a German physicist who formulated Ohm's Law in the 1820s. His work established a fundamental relationship between voltage, current, and resistance in electrical circuits. The name was officially adopted as a unit of measurement in 1861 by the International Electrical Congress in Paris. The concept of resistance has evolved from early experiments with electricity and magnetism, and the ohm has been central to the development of modern electrical engineering. The symbol 'ฮฉ' derived from the Greek alphabet, reflects the scientific community's tradition of using Greek letters in technical terminology, especially in physics and mathematics.
