Unit Explanations
Mho℧
Source UnitThe mho, symbolized as ℧, is a unit of electrical conductance in the International System of Units (SI), defined as the reciprocal of resistance measured in ohms (Ω). One mho is equivalent to one siemens (S), which is the standardized SI unit for conductance. Conductance quantifies how easily electric current can flow through a conductor when a voltage is applied. The relationship between conductance and resistance is given by the formula: G = 1/R, where G is the conductance in mhos and R is the resistance in ohms. Since electrical conductance is a measure of the ability of an object to conduct electric current, the larger the mho value, the better the conductor. Mhos are commonly used in various electrical engineering applications to characterize the conductive properties of materials and components.
Current Use
Today, the mho is utilized primarily in electrical engineering and related fields to describe the conductance of materials and components such as resistors, capacitors, and conductive pathways in circuits. It is particularly relevant in applications involving alternating current (AC) where impedance needs to be assessed. Various industries, including telecommunications, electronics, and power generation, rely on measurements of conductance in mhos for the design and analysis of circuits. Engineers may use this unit to evaluate the performance of electrical components, ensuring they meet required specifications for efficiency and safety. Notably, the mho is still prevalent in educational settings, particularly in physics and engineering courses that cover electrical concepts. In countries like the United States, the mho continues to be a recognized unit, while in many other nations, the siemens has become the dominant terminology. Nevertheless, both units are interchangeable, reflecting a shared understanding of electrical conductance across global engineering practices.
Fun Fact
The mho is one of the few units that is spelled backward (ohm).
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.

Definition
The mho, symbolized as ℧, is a unit of electrical conductance in the International System of Units (SI), defined as the reciprocal of resistance measured in ohms (Ω). One mho is equivalent to one siemens (S), which is the standardized SI unit for conductance. Conductance quantifies how easily electric current can flow through a conductor when a voltage is applied. The relationship between conductance and resistance is given by the formula: G = 1/R, where G is the conductance in mhos and R is the resistance in ohms. Since electrical conductance is a measure of the ability of an object to conduct electric current, the larger the mho value, the better the conductor. Mhos are commonly used in various electrical engineering applications to characterize the conductive properties of materials and components.
History & Origin
The term 'mho' originated in the late 19th century, emerging from the need to quantify electrical conductance, a concept that became more prominent with advancements in electrical engineering. As electrical systems proliferated, particularly in the development of telegraphy and later, electric power distribution, the measurement of how well a material could conduct electricity became essential. The reciprocal relationship between resistance and conductance was recognized, leading to the introduction of mho as a unit to denote conductance directly. The mho was particularly adopted in the United States and was used alongside other electrical units, facilitating clearer communication of conductance values in engineering.
Etymology: The word 'mho' is derived from 'ohm', the unit of electrical resistance, spelled backward.
