noun
- a unit of electrical resistance equal to the resistance of a conductor in which a current of one ampere is produced by a potential difference of one volt
Usage: physics; electrical engineering
Examples
- The resistor has a value of 100 ohms.
- Ohm’s law relates voltage, current, and resistance.
- The circuit requires a 50-ohm impedance.
- We measured the resistance in ohms using a multimeter.
- The speaker has an 8-ohm rating.
- Higher ohm values indicate greater electrical resistance.
