ohm
| Symbol: | ohm, W |
| Category: | Electric resistance |
| SI Equivalent: | 1 ohm |
| Dimension: | ML2T-3I-2 |
| System: | SI |
| Notes | |
| Named after the German physicist Georg Simon Ohm (1789-1854), the ohm is the unit of electrical resistance in the SI system. It is equal to the resistance that produces the potential difference of 1 volt when the current is 1 ampere. Equivalently, 1 ohm of resistance causes 1 watt of power dissipation when 1 ampere flows through it. | |
