Siemens (unit)

From Academic Kids

The siemens (symbol: S) is an SI derived unit of measurement for electric conductance, being the inverse of the ohm (Ω), named after Werner von Siemens.

<math>S = A/V<math>

  • S = siemens
  • A = amperes
  • V = volts

The forumla for computing conductance is as follows:

G = 1 / R = S

  • G = Conductance
  • R = Resistance (ohms, Ω)
  • S = siemens

Example: G = 1 / 6 Ω = 0.1667 S

Mho is a now eccentric name for this unit of electrical conductance, equal to 1 Ω−1. It is derived by spelling ohm backwards. Its symbol is the upside-down letter Ω <math>\mho<math> ℧ (Template:Uplusfirst2127). The term siemens is used universally in science and primarily in electrical applications, while mho is used primarily in electronic applications.
