## Conductance
|
||
|
||
**Conductance** is the reciprocal of [resistance](https://en.wikipedia.org/wiki/Electrical_resistance).
|
||
|
||
The SI unit of conductance ($G$)
|
||
is the [siemens](https://en.wikipedia.org/wiki/Siemens_(unit)) (S).
|
||
"Mho" (ohm backwards) is an unofficial name and should be avoided.
|
||
|
||
Like the ohm is also the unit of [reactance](https://en.wikipedia.org/wiki/Electrical_reactance) ($X$)
|
||
and [impedance](https://en.wikipedia.org/wiki/Electrical_impedance) ($Z$),
|
||
the siemens is also the unit of [susceptance](https://en.wikipedia.org/wiki/Electrical_susceptance) ($B$)
|
||
and [admittance](https://en.wikipedia.org/wiki/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.
