The henry is a derived unit based on four of the seven base units of the International System of Units: kilogram (kg), metre (m), second (s), and ampere (A). Expressed in combinations of SI units, the henry is: [ 3 ]

In physics, and electronics, the henry (symbol H) is the SI unit of inductance. [1] It is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction. (In England, Michael Faraday (1791–1867) discovered the same thing independently.

Henry, unit of either self-inductance or mutual inductance, abbreviated H, and named for the American physicist Joseph Henry. One henry is the value of self-inductance in a closed circuit or coil in which one volt is produced by a variation of the inducing current of one ampere per second.

The henry, symbol H, is the SI coherent derived unit of electrical inductance. It is the special name for the kg m 2 s −2 A -2 . One henry is the inductance of an electric circuit when an electric current, that is changing at one ampere per second, results in an electromotive force of one volt across the inductor.

A henry (H) is a unit of inductance, which is the mathematical representation of electromagnetic induction. The unit is named after American physicist Joseph Henry. When 1 ampere (A) of electric current is changing per second (s) within an electric circuit, 1 henry of inductance will produce a voltage equal to 1 volt (V) across the inductor.

2025年3月6日 · Subunits of Henry. Given that the Henry is a relatively large unit, inductances in practical circuits are often much smaller. Therefore, subunits of the Henry are commonly used: Millihenry (mH): One thousandth of a Henry, or (10^{-3}) H. Microhenry (μH): One millionth of a Henry, or (10^{-6}) H. Nanohenry (nH): One billionth of a Henry, or (10 ...

The henry is the International System of Units (SI) derived unit of electrical inductance, and it is named after the American physicist Joseph Henry. Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it.

A henry is a unit used to measure electrical inductance. The henry is the SI derived unit for electrical inductance in the metric system. Henries can be abbreviated as H; for example, 1 henry can be written as 1 H.

The henry (H) is the SI derived unit of electrical inductance. If a current of 1 ampere (A) flowing through a coil produces flux linkage of 1 weber (Wb) turn, that coil has a self-inductance of 1 henry.

The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI).
