Millihenry per second (mH/s) is a unit of measurement that expresses the rate of change of inductance in electrical circuits. It is a subunit of henry, where 1 millihenry equals 0.001 henries. This measurement is crucial in understanding how inductors behave in alternating current (AC) circuits, especially in applications involving inductive reactance.
The millihenry per second is standardized under the International System of Units (SI). It is derived from the henry, which is the SI unit of inductance. The symbol for millihenry is mH, and when expressed per second, it indicates the rate at which the inductance changes over time.
The concept of inductance was first introduced by Michael Faraday in the 19th century, and the unit was named after Joseph Henry, an American scientist who made significant contributions to the field of electromagnetism. Over time, as electrical engineering evolved, the need for smaller units like millihenry became apparent, allowing for more precise calculations in circuit design.
To illustrate the use of millihenry per second, consider an inductor with an inductance of 10 mH. If the current through this inductor changes at a rate of 2 A/s, the induced electromotive force (EMF) can be calculated using the formula:
[ \text{EMF} = -L \frac{di}{dt} ]
Where:
Thus, the induced EMF would be:
[ \text{EMF} = -0.01 \times 2 = -0.02 \text{ V} ]
Millihenry per second is commonly used in electrical engineering, particularly in the design and analysis of inductors in circuits. It helps engineers and technicians understand how inductors will respond to changes in current, which is essential for ensuring the stability and efficiency of electrical systems.
To utilize the millihenry per second tool effectively, follow these steps:
What is millihenry per second (mH/s)? Millihenry per second is a unit that measures the rate of change of inductance in electrical circuits, crucial for understanding inductive behavior.
How do I convert millihenries to henries? To convert millihenries to henries, divide the value in millihenries by 1000. For example, 10 mH equals 0.01 H.
What is the significance of inductance in electrical circuits? Inductance is vital for determining how circuits respond to changes in current, affecting performance in AC applications.
Can I use this tool for other unit conversions? While this tool is specialized for millihenry per second calculations, you can explore other tools on our website for conversions like tonne to kg or bar to pascal.
How does the rate of change of current affect inductance? A higher rate of change of current through an inductor results in a greater induced electromotive force, which can influence circuit behavior significantly.

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.
