In the field of physics, the term ‘Siemens’ (often denoted by the symbol’s’) can be defined as the unit of electric susceptance, electric admittance, and electric conductance. As per the International System of Units (often abbreviated to SI), one siemens can be defined as the reciprocal of one ohm. It can be noted that the term ‘mho’, which features the backward spelling of the term ‘ohm’, is often used as an alternative to the term ‘siemens’. The SI unit of electric susceptance, electric admittance, and electric conductance is named after the German inventor and electrical engineer Ernst Werner von Siemens. The upside-down Greek letter omega often denotes it. It is important to note that the SI base units of siemens are kilogram-1, metre-2, second3, and ampere2 (or kg-1.m-2.s3.A2).
