DEFINITION For a device with Electrical Resistance ''R'', the Conductance ''G'' is defined as where
The unit siemens for the conductance ''G'' is defined by : Note that the last term is in SI Base Units where A is the abbreviation for Ampere , the unit of Electric Current ; kg is the abbreviation for Kilogram ; m is the abbreviation for Metre ; and s is the abbreviation for the time unit Second . So for a device with conductance one siemens, then the Electric Current through it with one Volt across it is one Ampere , and for each extra volt across it the electric current through it increases by one ampere. Example: The conductance of a resistor with resistance six Ohm s is ''G'' = 1/(6 Ω) = 0.166• S. SI MULTIPLES MHO The siemens is equivalent to the previously used term ''mho'' unit, which was derived from spelling ''ohm'' backwards and written with an upside-down capital ) it is common to write the symbol for Second incorrectly as S instead of s, causing potential confusion. |
