Mho

℧

Definition

An older unit of electric conductance equal to one siemens, representing the inverse of resistance. The name "mho" is "ohm" spelled backwards, reflecting its relationship to resistance.

History/Origin

Created as the inverse of the ohm unit for measuring electrical conductance. The name "mho" (ohm spelled backwards) was used before the adoption of the siemens as the official SI unit of conductance.

Current Use

Still used in some electrical engineering contexts and older technical literature. Gradually being replaced by the siemens unit in modern electrical engineering practice and international standards.

Quantized Hall Conductance

e²/h

Definition

A fundamental unit of electric conductance based on quantum mechanics, equal to approximately 3.87405E-5 siemens. Used in quantum Hall effect measurements and fundamental physics research.

History/Origin

Derived from the quantum Hall effect discovered by Klaus von Klitzing in 1980. The quantized Hall conductance represents a fundamental constant in quantum mechanics and is used in precision electrical measurements.

Current Use

Used in fundamental physics research, quantum Hall effect studies, and precision electrical measurements. Essential for defining the ohm in terms of fundamental physical constants and quantum mechanical principles.
