\mhoThe symbol \mho is used to represent the unit of electrical conductance, which is the reciprocal of resistance. It is equivalent to the siemens (S) and is sometimes used in theoretical contexts or older literature.
Electrical conductance of a component is 5 mho.
G = 5 \, \mhoAdmittance of a circuit is 0.02 mho.
Y = 0.02 \, \mhoConductance expressed as the reciprocal of resistance in mho.
\text{Conductance} = \frac{1}{R} \, \mho
