Unit Explanations
ConductanceS
Source UnitConductance, measured in siemens (S), quantifies the ease with which electric current flows through a conductor when a voltage is applied. It is the reciprocal of resistance, meaning a high conductance indicates low resistance. The unit siemens was introduced to honor the German engineer Ernst Werner von Siemens, who contributed significantly to the development of electrical engineering. Mathematically, conductance can be expressed as G = I/V, where G is conductance, I is the current in amperes, and V is the voltage in volts. This relationship highlights the direct proportionality of current flow to voltage when conductance is constant.
Current Use
Conductance is widely used in electrical engineering, physics, and materials science to describe the performance of conductors and circuits. It is a crucial parameter in the design of electrical systems, particularly in analyzing and optimizing the efficiency of power distribution networks and electronic devices. Additionally, conductance plays a significant role in the assessment of materials used in various industries, including telecommunications and automotive sectors.
Fun Fact
The siemens was previously known as mho, which is ohm spelled backward, reflecting the relationship between conductance and resistance.
AbmhoabΩ
Target UnitThe abmho (symbol: abΩ) is a unit of electrical conductance in the centimeter-gram-second (CGS) system of units. It measures how easily electric current flows through a material when a voltage is applied. One abmho is defined as the conductance that allows one ampere of current to flow when one volt is applied across the conductor. The abmho is equivalent to the reciprocal of the abohm, which is a unit of electrical resistance. This relationship is crucial in understanding the behavior of electrical circuits and materials. Given its roots in the CGS system, the abmho is less commonly used today compared to SI units, but it remains relevant in specific contexts related to historical electrical engineering practices and certain scientific calculations.
Current Use
Although the abmho is not widely used in modern applications, it holds historical significance in the study and understanding of electrical engineering principles. It is primarily of interest in academic contexts, particularly when studying the history of electricity and electrical units. In some specialized fields, such as physics and electrical engineering, the abmho may still be used in theoretical discussions or when converting historical data into contemporary units. Countries that utilize the abmho in historical contexts include the United States and the United Kingdom, particularly in academic institutions that focus on the foundations of electrical engineering. In these settings, the abmho serves as a reminder of the evolution of electrical measurement standards and the development of the field itself.
Fun Fact
The abmho is rarely used today, but it was once a standard in electrical engineering education.

Definition
Conductance, measured in siemens (S), quantifies the ease with which electric current flows through a conductor when a voltage is applied. It is the reciprocal of resistance, meaning a high conductance indicates low resistance. The unit siemens was introduced to honor the German engineer Ernst Werner von Siemens, who contributed significantly to the development of electrical engineering. Mathematically, conductance can be expressed as G = I/V, where G is conductance, I is the current in amperes, and V is the voltage in volts. This relationship highlights the direct proportionality of current flow to voltage when conductance is constant.
History & Origin
The concept of conductance emerged in the 19th century as electrical engineering became more prominent. The unit siemens was adopted in 1881 during the International Electrical Congress held in Paris. The recognition of conductance as a vital electrical parameter facilitated advancements in circuit theory and electronic devices.
Etymology: The term 'siemens' is derived from the name of Ernst Werner von Siemens, a significant figure in electrical engineering and co-founder of the Siemens company, which played a crucial role in the development of telegraphy and electrical engineering.

History & Origin
The abmho was introduced in the late 19th century as part of the CGS system. This was a time when electrical engineering was emerging as a distinct field, and various units were being developed to measure electrical properties. The term 'abmho' was derived from 'mho,' which itself is the reverse spelling of 'ohm,' the unit of resistance. The abmho was devised to facilitate calculations in electrical engineering, particularly in telegraphy and early telecommunication technologies. Its introduction was significant during a period marked by rapid advancements in electrical theory and practice.
Etymology: The name 'abmho' comes from 'ab' which indicates the CGS system, and 'mho,' a term coined in the 1880s to represent conductance, being the reciprocal of resistance.
Current Use
Although the abmho is not widely used in modern applications, it holds historical significance in the study and understanding of electrical engineering principles. It is primarily of interest in academic contexts, particularly when studying the history of electricity and electrical units.
