Ohm

ōm

Meaning & Definition

noun

The unit of electrical resistance in the International System of Units (SI), symbolized as 'Ω', defined as the resistance between two points of a conductor when a constant potential difference of one volt applied to those points produces a current of one ampere.

The resistor has a value of five ohms.

The resistance of a conductor in which a current of one ampere is maintained by a potential difference of one volt.

The circuit showed a total resistance of 10 ohms.

A measurement used in various fields of electrical engineering and physics to quantify resistance.

When calculating the total resistance in a series circuit, you simply add the ohms of each component.

A reference value for determining the performance characteristics of electronic components.

The amplifier operates efficiently at an impedance of eight ohms.

A unit in the study of electricity and electronics that provides insight into the functionality and capabilities of devices.

To get accurate readings, ensure your multimeter is set to measure ohms.

Etymology

Named after Georg Simon Ohm, a German physicist known for his work in electrical circuit theory.
