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 megohm (MĪ©) is a derived unit of electrical resistance in the International System of Units (SI), representing one million ohms (1 MĪ© = 1,000,000 Ī©). It is used to quantify the resistance that an electrical component or circuit presents to the flow of electric current. Resistance is a measure of the opposition to the flow of electric charge, and it is a crucial parameter in electrical engineering, electronics, and physics.

The unit is typically represented by the symbol 'MĪ©' and is widely used in both industry and academia.
History & Origin
The concept of resistance as a measurable quantity emerged in the late 19th century with the work of physicists like Georg Simon Ohm, who formulated Ohm's Law in 1827. This law established the relationship between voltage, current, and resistance, paving the way for the formal definition of resistance units. The ohm, the base unit for electrical resistance, was derived from Ohm's Law, where 1 ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt applied across it results in a current of one ampere. During the 20th century, as electrical engineering advanced and the demand for measuring high resistance increased, the megohm became an essential unit. It was officially recognized and standardized as part of the SI system, facilitating communication and consistency across scientific and engineering disciplines.
Etymology: The term 'megohm' is derived from the prefix 'mega-', which means one million, and 'ohm', named after the German physicist Georg Simon Ohm, who established the foundational principles of electrical resistance.
