Conductance
Conductance is the reciprocal of resistance.
The SI unit of conductance (G)
is the siemens (S).
"Mho" (ohm backwards) is an unofficial name and should be avoided.
Like the ohm is also the unit of reactance (X)
and impedance (Z),
the siemens is also the unit of susceptance (B)
and admittance (Y),
their respective reciprocals.
For my purposes, conductance is generally a far more practical quantity than resistance, owing to that it increases with wire area and cost like ampacity.

V = \frac{I}{G}, \quad G = \frac{I}{V}, \quad I = G \times V
