Unit Explanations
OhmΩ
Source UnitThe ohm (Ω) is the SI unit of electrical resistance, named after the German physicist Georg Simon Ohm. It is defined as the amount of resistance that allows a current of one ampere to flow when a voltage of one volt is applied across it. This relationship can be expressed mathematically using Ohm's Law, which states that V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms. The ohm is a crucial unit in electrical engineering and physics, as it enables the quantification of how much a material opposes the flow of electric current, thus playing a vital role in circuit design and analysis.
Current Use
The ohm is widely used in various industries, including electronics, telecommunications, and electrical engineering. In electronics, components such as resistors are rated in ohms, indicating their resistance to current flow. For instance, in telecommunications, understanding resistance is crucial for signal integrity and transmission quality over cables. In power systems, the measurement of resistance helps in assessing the efficiency of electrical circuits. Countries around the world, including the United States, Germany, and Japan, utilize the ohm in both academic and practical applications, ensuring that electrical specifications adhere to international standards, thus promoting safety and interoperability in electrical designs.
Fun Fact
Georg Simon Ohm was initially a teacher and faced many challenges before his work gained recognition.
StatohmΩs
Target UnitThe statohm is a unit of electrical resistance that is used primarily in the centimeter-gram-second (CGS) system of units. It is defined as the resistance between two points in a conductor when a potential difference of one statvolt (1 statV) causes a current of one statampere (1 statA) to flow through the conductor. The relationship between the different units of electricity is foundational to understanding the behavior of electrical systems, particularly in the context of electrostatics. The statohm is part of the broader set of electromagnetic units that include the statvolt and statampere, and it is particularly relevant in theoretical physics and certain engineering applications, particularly those involving low-scale electrostatic phenomena.
Current Use
Today, the statohm is not commonly used in everyday electrical engineering or industrial applications, having been largely replaced by the ohm in most parts of the world. However, it remains a significant unit within fields that study electrostatics and theoretical physics, particularly in the context of materials science and semiconductor research. Some academic environments and research laboratories may still utilize the statohm when teaching principles of electromagnetism and electrostatics. Countries that continue to engage with CGS units in their research, particularly in physics and engineering, may reference the statohm. Its significance in defining the relationships between electric charge, voltage, and resistance makes it relevant for educational purposes in both advanced high school and university-level physics courses.
Fun Fact
The statohm is rarely used in everyday electrical engineering, making it somewhat of a niche measurement.

Ohm
electric • SI Unit
Definition
The ohm (Ω) is the SI unit of electrical resistance, named after the German physicist Georg Simon Ohm. It is defined as the amount of resistance that allows a current of one ampere to flow when a voltage of one volt is applied across it. This relationship can be expressed mathematically using Ohm's Law, which states that V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms. The ohm is a crucial unit in electrical engineering and physics, as it enables the quantification of how much a material opposes the flow of electric current, thus playing a vital role in circuit design and analysis.
History & Origin
The term 'ohm' was established in 1861 during the International Electrical Congress in Paris, where it was named in honor of Georg Simon Ohm, who published his pivotal work, 'Die galvanische Kette, mathematisch bearbeitet' (The Galvanic Circuit, Mathematically Treated) in 1827. Ohm's work laid the groundwork for understanding the relationship between voltage, current, and resistance, which became fundamental to electrical engineering. The adoption of the term helped standardize the unit of resistance across different scientific and engineering disciplines.
Etymology: The word 'ohm' is derived from the surname of the German physicist Georg Simon Ohm, reflecting his contributions to the field of electrical resistance.

Definition
The statohm is a unit of electrical resistance that is used primarily in the centimeter-gram-second (CGS) system of units. It is defined as the resistance between two points in a conductor when a potential difference of one statvolt (1 statV) causes a current of one statampere (1 statA) to flow through the conductor.

The statohm is part of the broader set of electromagnetic units that include the statvolt and statampere, and it is particularly relevant in theoretical physics and certain engineering applications, particularly those involving low-scale electrostatic phenomena.
History & Origin
The statohm originated in the late 19th century as part of the CGS system of units, which was developed to provide a coherent framework for measurements in physics. This system was created to facilitate the study of electromagnetism and electrostatics, areas that were rapidly advancing during this period. The statohm specifically arose from the need to quantify electrical resistance in a manner that was consistent with the other units in the CGS system. The advent of the statohm marked a significant step in the evolution of electrical measurement, as it provided a means to express resistance in a system that was widely used in scientific research and engineering at the time.
Etymology: The term 'statohm' derives from the combination of 'stato-', referring to static electricity, and 'ohm', named after the German physicist Georg Simon Ohm, who formulated Ohm's Law.
