Simens

Simens (znak: S) mjerna je jedinica za električnu vodljivost u Međunarodnom sustavu jedinica (SI).[1] Ime je dobila prema njemačkom izumitelju i industrijalcu Ing. Werneru von Siemensu, a 1971. je prihvaćena kao izvedena mjerna jedinica SI.

Na angloameričkom govornom području je u elektronici za ovu jedinicu uobičajen i zastarjeli naziv mho (znak: ).

Definicija

Za uređaj s električnim otporom R električna vodljivost G definirana je kao:

gdje je:

Jedinica za vodljivost simens definirana je kao:

1 S = 1 Ω-1 = 1 A/V = 1 A2/W = 1 kg−1·m−2·s3·A2

Primjer: Vodljivost otpornika otpora 5 oma je: G = 1/(5 Ω) = 0,2 S.
