Si base unit of ohm

WebAn SI-unit that disturbs electrical current. Symbol: Ω / Base data: electrical resistance. SI derived units. Electrical resistance between two points of a conductor when a constant potential difference of 1V, applied to these points, produces in the conductor a current of 1A. WebFeb 1, 2001 · The realization of the ohm from the calculable capacitor at NBS in terms of the SI units of length and time was evaluated to have a relative standard uncertainty of 0.03 × 10 −6. Shields et al. [ 28 ] reported the second NIST realization of the ohm and farad in 1989 using the same system after making several improvements.
