The millihenry (mH) is a unit of inductance in the International System of Units (SI). It represents one-thousandth of a henry, the standard unit of inductance. Inductance is a property of an electrical circuit that opposes changes in current, making it a crucial concept in electrical engineering and physics.
The millihenry is standardized under the SI system, ensuring consistency and accuracy in measurements across various applications. This standardization is vital for engineers and scientists who rely on precise calculations in their work.
The concept of inductance was first introduced by Michael Faraday in the 19th century. The henry was named after the American scientist Joseph Henry, who made significant contributions to the field of electromagnetism. Over time, the millihenry emerged as a practical subunit, allowing for more manageable calculations in circuits where inductance values are often small.
To illustrate the use of the millihenry, consider a circuit with an inductor rated at 10 mH. If the current flowing through the inductor changes at a rate of 2 A/s, the induced voltage can be calculated using the formula:
[ V = L \cdot \frac{di}{dt} ]
Where:
For our example: [ V = 10 \times 10^{-3} \cdot 2 = 0.02 , \text{V} ]

The sthenry (sH) is a unit of inductance in the International System of Units (SI). It measures the ability of a conductor to induce an electromotive force (emf) in itself or in another conductor when the current flowing through it changes. Understanding inductance is crucial for various applications in electrical engineering, particularly in designing circuits and understanding electromagnetic fields.
The sthenry is standardized under the SI units, where 1 sH is defined as the inductance that produces an electromotive force of 1 volt when the current through it changes at a rate of 1 ampere per second. This standardization ensures consistency and accuracy in measurements across different applications and industries.
The concept of inductance dates back to the early 19th century when scientists like Michael Faraday and Joseph Henry explored electromagnetic induction. The term "henry" was later adopted as the standard unit of inductance, named in honor of Joseph Henry. The sthenry is a derived unit, reflecting the need for smaller measurements in various electronic applications.
To illustrate the use of the sthenry, consider a circuit with an inductance of 2 sH. If the current through this inductor changes from 0 to 3 A in 2 seconds, the induced emf can be calculated using the formula:
[ \text{emf} = L \times \frac{\Delta I}{\Delta t} ]
Where:
Thus, the induced emf would be:
[ \text{emf} = 2 , \text{sH} \times \frac{3 , \text{A}}{2 , \text{s}} = 3 , \text{V} ]
The sthenry is commonly used in electrical engineering, particularly in the design and analysis of inductors, transformers, and various electronic components. Understanding and converting inductance measurements can help engineers optimize circuit designs and improve performance.
