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.
