Unit Explanations
SiemensS
Source UnitThe siemens (symbol: S) is the SI unit of electrical conductance, defined as the reciprocal of resistance in ohms. One siemens is equivalent to one ampere per volt, which can be expressed as S = A/V. This unit is used to measure how easily electricity can flow through a material or circuit. The siemens is a derived unit, belonging to the International System of Units (SI), and was adopted in 1960 during the 11th General Conference on Weights and Measures. It is named after the German inventor and electrical engineer Werner von Siemens, who made significant contributions to the development of electrical engineering.
Current Use
Today, the siemens is widely utilized across various industries for measuring electrical conductance. It is an essential unit in electrical engineering, especially in the design and analysis of circuits. The telecommunications industry employs siemens to assess the conductance of transmission lines and cables, ensuring efficient signal transmission. In the field of electronics, components such as resistors, capacitors, and inductors are evaluated using siemens to determine their behavior in circuits. Furthermore, in the realm of materials science, researchers use this unit to characterize the electrical properties of materials, aiding in the development of conductive materials for various applications. Countries worldwide, including the USA, Germany, and Japan, utilize the siemens in both educational and professional settings, reinforcing its importance in global electrical engineering practices.
Fun Fact
The symbol for siemens, 'S', is a tribute to the inventor Werner von Siemens.
ESU of Resistanceesu
Target UnitThe electrostatic unit (esu) of resistance is a unit of measurement in the centimeter-gram-second (CGS) system, primarily used in theoretical physics and electrical engineering. It is defined such that one esu of resistance equals the resistance that allows a current of one esu of current to flow under a potential difference of one esu of potential. Specifically, 1 esu of resistance is equivalent to approximately 3.336 x 10^9 ohms in the International System of Units (SI). This unit is part of the broader electrostatic unit system, which is based on the forces between charged bodies. The esu of resistance is significant in contexts involving electrostatic fields and potential differences, particularly in historical scientific literature.
Current Use
While the esu of resistance is largely of historical interest, it is occasionally referenced in theoretical studies of electrostatics and in certain educational contexts. It is primarily found in discussions surrounding classical electromagnetic theory and is sometimes utilized in specialized academic research where the CGS system is still employed. Countries that continue to reference the CGS system, such as the United States in some scientific fields, may encounter the esu. Additionally, the esu is sometimes mentioned in literature pertaining to the history of electromagnetism, illustrating the evolution of electrical measurements. However, its practical applications in modern engineering and technology are minimal, as the SI system has become the dominant framework for electrical measurements globally.
Fun Fact
The esu of resistance is rarely used in modern electrical engineering, with the ohm being the preferred unit.

Siemens
electric • SI Unit
Definition
The siemens (symbol: S) is the SI unit of electrical conductance, defined as the reciprocal of resistance in ohms. One siemens is equivalent to one ampere per volt, which can be expressed as S = A/V. This unit is used to measure how easily electricity can flow through a material or circuit. The siemens is a derived unit, belonging to the International System of Units (SI), and was adopted in 1960 during the 11th General Conference on Weights and Measures. It is named after the German inventor and electrical engineer Werner von Siemens, who made significant contributions to the development of electrical engineering.
History & Origin
The concept of electrical conductance dates back to the early experiments with electricity, particularly in the 19th century. The formal definition and measurement of conductance emerged as researchers like Georg Simon Ohm established the relationship between voltage, current, and resistance. Ohm's Law (V = IR) laid the groundwork for understanding electrical circuits. The need for a standardized unit came as electrical systems became more complex, and the importance of conductance in circuit design and analysis increased. The siemens was introduced as a unit of conductance to formalize this aspect of electrical engineering.
Etymology: The term 'siemens' is derived from the name of Werner von Siemens, a prominent figure in the field of electrical engineering, reflecting his significant contributions to the development of electrical systems and technology.

Definition
The electrostatic unit (esu) of resistance is a unit of measurement in the centimeter-gram-second (CGS) system, primarily used in theoretical physics and electrical engineering. It is defined such that one esu of resistance equals the resistance that allows a current of one esu of current to flow under a potential difference of one esu of potential.

This unit is part of the broader electrostatic unit system, which is based on the forces between charged bodies. The esu of resistance is significant in contexts involving electrostatic fields and potential differences, particularly in historical scientific literature.
History & Origin
The esu of resistance originated in the late 19th century as part of the CGS system, which was established to provide a consistent framework for measuring physical quantities. The need for a unit of resistance arose from the burgeoning field of electromagnetism, as scientists sought to quantify and understand electrical phenomena in a more systematic manner. Early experiments with static electricity and electrical circuits necessitated the creation of standardized units, leading to the adoption of the electrostatic unit system, where resistance was defined in terms of charge, current, and voltage in a way that was consistent with electrostatic principles.
Etymology: The term 'electrostatic' derives from the Greek words 'ēlektron,' meaning amber (which was known for its static electricity) and 'statikos,' meaning stationary or standing. Together, they denote the study of stationary electric charges.
