Ohm (symbol Ω) is the electrical unit of resistance.
The Ohm unit was named after George Simon Ohm.
1Ω = 1V / 1A = 1J ⋅ 1s / 1C2
| name | symbol | conversion | example |
|---|---|---|---|
| milli-ohm | mΩ | 1mΩ = 10-3Ω | R0 = 10mΩ |
| ohm | Ω | - |
R1 = 10Ω |
| kilo-ohm | kΩ | 1kΩ = 103Ω | R2 = 2kΩ |
| mega-ohm | MΩ | 1MΩ = 106Ω | R3 = 5MΩ |
Ohmmeter is a measurement device that measures resistance.
