About Siemens
The siemens (S) is the SI derived unit of electrical conductance, equal to 1 ampere per volt (1 A/V = 1 Ω⁻¹ = 1 kg⁻¹·m⁻²·A²·s³), named after Werner von Siemens (1816-1892). Also known as the mho (℧), it describes how easily current flows: a 1 Ω resistor has 1 S conductance. Power MOSFETs are characterised by 1/Rₛ_ₒₙ in siemens; large RF transistors operate with transconductance of 1-10 S.
About Absiemens
The absiemens (abS) is the conductance unit of the CGS-EMU system, equal to 1/abΩ = 1/(10⁻⁹ Ω) = 10⁹ S, exactly identical to 1 GS in SI. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts; 1 abS corresponds to the conductance of a 1 nΩ connection typical of large cryogenically cooled bus joints or welded thick-copper structures. 1 abS = 10⁹ S = 1 GS.
