The Ohm (Ω) is the standard unit of electrical resistance in the International System of Units (SI). It quantifies how strongly a material opposes the flow of electric current. Understanding resistance is crucial for anyone working with electrical circuits, as it directly affects the performance and safety of electrical systems.
The Ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt applied to those points produces a current of one ampere. This standardization ensures consistency and reliability in electrical measurements across various applications and industries.
The term "Ohm" is named after the German physicist Georg Simon Ohm, who formulated Ohm's Law in the 1820s. His work laid the foundation for electrical engineering and the study of circuits. Over the years, the understanding and application of Ohm's Law have evolved, leading to advancements in technology and electrical systems.
To illustrate the use of Ohms, consider a simple circuit with a voltage of 10 volts and a current of 2 amperes. Using Ohm's Law (V = I × R), we can calculate the resistance:
Ohms are widely used in various fields, including electronics, telecommunications, and electrical engineering. They help in designing circuits, troubleshooting electrical issues, and ensuring safety standards are met.

The megaohm (MΩ) is a unit of electrical resistance that is equal to one million ohms (1,000,000 Ω). It is commonly used in electrical engineering and physics to measure the resistance of materials and components in electrical circuits. Understanding resistance is crucial for designing and analyzing electrical systems, ensuring safety, and optimizing performance.
The megaohm is part of the International System of Units (SI) and is derived from the ohm, which is the standard unit of resistance. The symbol for megaohm is MΩ, and it is widely recognized in scientific literature and engineering practices. The use of megaohms allows for easier representation of large resistance values, making calculations and comparisons more manageable.
The concept of electrical resistance was first introduced by Georg Simon Ohm in the 1820s, leading to the formulation of Ohm's Law. As electrical technology advanced, the need to measure higher resistance values became apparent, resulting in the adoption of the megaohm as a standard unit. Over the years, the megaohm has played a vital role in the development of electrical systems, from early telegraph lines to modern electronic devices.
To convert resistance values from ohms to megaohms, simply divide the value in ohms by 1,000,000. For example, if you have a resistance of 5,000,000 ohms, the conversion to megaohms would be:
[ 5,000,000 , \text{Ω} \div 1,000,000 = 5 , \text{MΩ} ]
Megaohms are particularly useful in applications involving high resistance measurements, such as insulation testing, circuit design, and troubleshooting. They help engineers and technicians assess the quality and safety of electrical components, ensuring that systems operate efficiently and without risk of failure.
