Definition: Siemens is the unit of electric susceptibility, electric admittance, and electric conductance.
According to the International System of Units (commonly shortened to SI), one siemens would be the reciprocal of one ohm. the SI base units of siemens is or
The electric susceptance, admittance, and conductance SI units are designated after the German inventor as well as electrical engineer Ernst Werner von Siemens.
Therefore, It should be noted that the term mho,' which seems to be a backward pronunciation of the expression 'ohm,' is frequently used as an alternative to the phrase siemens.
