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.

Resistivity, denoted by the symbol ρ (rho), is a fundamental property of materials that quantifies how strongly they resist the flow of electric current. It is measured in ohm-meters (Ω·m) and is crucial for understanding electrical conductivity in various materials. The lower the resistivity, the better the material conducts electricity, making this measurement vital in electrical engineering and materials science.
Resistivity is standardized under various conditions, including temperature and material composition. The International System of Units (SI) defines the resistivity of a material at a specific temperature, typically 20°C for metals. This standardization allows for consistent measurements across different applications and industries.
The concept of resistivity has evolved significantly since its inception in the 19th century. Early scientists, such as Georg Simon Ohm, laid the groundwork for understanding electrical resistance. Over time, advancements in material science and electrical engineering have refined our understanding of resistivity, leading to the development of more efficient materials and technologies.
To calculate resistivity, use the formula: [ ρ = R \times \frac{A}{L} ] Where:
For example, if a copper wire has a resistance of 5 Ω, a cross-sectional area of 0.001 m², and a length of 10 m, the resistivity would be: [ ρ = 5 \times \frac{0.001}{10} = 0.0005 , Ω·m ]
Resistivity is used extensively in electrical engineering, electronics, and materials science. It helps engineers select appropriate materials for wiring, circuit design, and other applications where electrical conductivity is crucial. Understanding resistivity also aids in the analysis of thermal and electrical properties of materials.
