The Henry (H) is the standard unit of inductance in the International System of Units (SI). It measures the ability of a coil or circuit to store energy in a magnetic field when an electric current flows through it. Understanding inductance is crucial for various applications in electronics, electrical engineering, and physics.
A henry is defined as the inductance of a circuit in which a change in current of one ampere per second induces an electromotive force of one volt. This fundamental relationship is essential for understanding how inductors function in circuits.
The henry is standardized under the International System of Units (SI) and is widely recognized in scientific and engineering communities. It is crucial for ensuring consistent measurements across various applications, from simple circuits to complex electrical systems.
The unit is named after the American scientist Joseph Henry, who made significant contributions to the field of electromagnetism in the 19th century. His discoveries laid the groundwork for modern electrical engineering, and the henry was adopted as a unit of inductance in 1861.
To illustrate the concept of inductance, consider a circuit with an inductor of 2 henries. If the current through the inductor changes from 0 to 3 amperes in 1 second, the induced voltage can be calculated using the formula: [ V = L \frac{di}{dt} ] Where:
Substituting the values: [ V = 2 , H \times \frac{3 , A - 0 , A}{1 , s} = 6 , V ]
The henry is commonly used in electrical engineering to design and analyze circuits that involve inductors, transformers, and other components that rely on magnetic fields. Understanding this unit is essential for anyone working in electronics or electrical systems.

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} ]
