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 milliohm (mΩ) is a subunit of electrical resistance in the International System of Units (SI). It is equal to one-thousandth of an ohm (Ω), which is the standard unit of electrical resistance. The milliohm is particularly useful in applications where very low resistance values are measured, such as in electrical circuits and components.
The milliohm is standardized under the SI units, ensuring consistency and accuracy in measurements across various applications. It is commonly used in electrical engineering, electronics, and physics to quantify resistance in low-resistance scenarios.
The concept of electrical resistance was first introduced by Georg Simon Ohm in the 1820s, leading to the formulation of Ohm's Law. As technology advanced, the need for measuring lower resistance values became apparent, resulting in the adoption of subunits like the milliohm. Today, the milliohm is widely used in industries ranging from telecommunications to automotive engineering.
To illustrate the use of milliohms, consider a circuit where a resistor has a resistance of 0.005 Ω. To convert this value into milliohms, you would multiply by 1,000: [ 0.005 , \Omega \times 1000 = 5 , m\Omega ] This conversion is essential for precise measurements in low-resistance applications.
