Unit H
Name henry
Category Inductance
Details In the field of electromagnetism, inductance is a property of an electrical conductor that quantifies the amount of magnetic flux that the conductor generates due to the flow of electrical current through it. The unit of measurement for inductance is the henry (symbol: H), named after the American scientist Joseph Henry.

A conductor has an inductance of one henry (1 H) when a current change of one ampere per second (1 A/s) induces an electromotive force (EMF) of one volt (1 V) across the conductor. In other words, an inductor with an inductance of 1 H will generate 1 V of voltage across its terminals when the current flowing through it increases or decreases at a rate of 1 A/s.

Inductance plays a significant role in various electrical circuits, such as transformers, solenoids, inductors, and motors. In these applications, the inductance property of the conductors is utilized to store energy in the magnetic field and manipulate the behavior of the electrical circuits. It is also an essential parameter in the design and analysis of alternating current (AC) circuits, resonant circuits, and filters.
