Is é Ohm (siombail Ω) an t-aonad friotaíochta leictreach.
Ainmníodh an t-aonad Ohm i ndiaidh George Simon Ohm.
1 Ω = 1V / 1A = 1J ⋅ 1s / 1C 2
| ainm | siombail | tiontú | sampla |
|---|---|---|---|
| milli-ohm | mΩ | 1mΩ = 10 -3 Ω | R 0 = 10mΩ |
| ohm | Ω | - |
R 1 = 10Ω |
| kilo-ohm | kΩ | 1kΩ = 10 3 Ω | R 2 = 2kΩ |
| mega-ohm | MΩ | 1MΩ = 10 6 Ω | R 3 = 5MΩ |
Is gléas tomhais é Ohmmeter a thomhaiseann friotaíocht.
