The ohm (Ω) is the standard unit of electrical resistance in the International System of Units (SI). It quantifies how much a material opposes the flow of electric current. One ohm is defined as the resistance that allows one ampere of current to flow when a voltage of one volt is applied across it. This fundamental unit plays a crucial role in electrical engineering, physics, and various applications in everyday life.
The ohm is standardized based on the physical properties of materials and is defined by the relationship between voltage, current, and resistance as described by Ohm's Law. This law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). The formula is expressed as: [ V = I \times R ]
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 the field of electrical engineering. Over the years, the definition of the ohm has evolved with advancements in technology and measurement techniques, leading to the precise standards we use today.
To illustrate the concept of ohms, consider a circuit with a voltage of 12 volts and a current of 3 amperes. Using Ohm's Law: [ R = \frac{V}{I} = \frac{12V}{3A} = 4Ω ] This means the circuit has a resistance of 4 ohms.
Ohms are widely used in various applications, including electrical circuits, electronics, and telecommunications. Understanding resistance is essential for designing circuits, troubleshooting electrical issues, and ensuring safety in electrical systems.

The megaohm (MΩ) is a unit of electrical resistance in the International System of Units (SI). It represents one million ohms (1 MΩ = 1,000,000 Ω). This unit is commonly used in various electrical and electronic applications to measure resistance, which is crucial for understanding how electrical circuits function.
The megaohm is standardized under the SI system, ensuring consistency and reliability in measurements across various fields, including engineering, physics, and electronics. This standardization is essential for professionals who require precise measurements for their projects.
The concept of electrical resistance was first introduced by Georg Simon Ohm in the 1820s, leading to the formulation of Ohm's Law. Over the years, as technology advanced, the need for measuring resistance in larger scales became apparent, leading to the adoption of the megaohm as a standard unit. Today, the megaohm is widely used in industries such as telecommunications, automotive, and manufacturing.
To convert resistance from ohms to megaohms, simply divide the resistance value by 1,000,000. For instance, 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 high-resistance applications, such as insulation testing and circuit design. Engineers and technicians often rely on this unit to ensure that components can handle the required resistance levels without failure.
