Emu of Resistanceemu
Target UnitThe emu (electromagnetic unit) of resistance is a derived unit of electrical resistance in the centimeter-gram-second (CGS) system of units. Specifically, it is defined as the resistance that allows a current of one emu of magnetic flux change to result in one volt across a circuit. This unit is particularly useful in contexts involving electromagnetic phenomena and is integral in fields such as physics and engineering. The emu provides a way to quantify resistance in circuits influenced by magnetic fields, allowing for precision in calculations related to inductance and impedance, which are crucial in designing electrical systems. Its relevance persists despite the dominance of the SI system, especially in specialized scientific applications.
Current Use
The emu of resistance is primarily utilized in the fields of physics and electrical engineering, particularly in contexts where electromagnetic interactions are analyzed. It plays a crucial role in theoretical frameworks and experimental setups that investigate properties of materials under the influence of magnetic fields. Industries such as telecommunications, aerospace, and renewable energy heavily leverage the emu to design components that require precise electromagnetic properties. Countries with advanced research in electromagnetism, such as the United States, Germany, and Japan, often employ the emu in academic and industrial applications. The emu is also relevant in developing magnetic resonance imaging (MRI) technology, where understanding resistance in magnetic fields is essential for image clarity and accuracy.
Fun Fact
The emu is less commonly used today due to the dominance of the SI system, but it remains significant in specific scientific fields.

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.
