Meaning & Definition of word "Ohm"
Ohm
ōm
noun:
- 1. 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.
- Example: The resistor has a value of five ohms.
- 2. The resistance of a conductor in which a current of one ampere is maintained by a potential difference of one volt.
- Example: The circuit showed a total resistance of 10 ohms.
- 3. A measurement used in various fields of electrical engineering and physics to quantify resistance.
- Example: When calculating the total resistance in a series circuit, you simply add the ohms of each component.
- 4. A reference value for determining the performance characteristics of electronic components.
- Example: The amplifier operates efficiently at an impedance of eight ohms.
- 5. A unit in the study of electricity and electronics that provides insight into the functionality and capabilities of devices.
- Example: To get accurate readings, ensure your multimeter is set to measure ohms.
