Question

Define $1$ henry.

Answer 1

Hint The henry is the SI unit of the inductance; the name henry is given when it is invented by the American scientist Joseph Henry. Most of the time in physics, henry is used to represent the unit of the electrical inductance. And the henry is denoted as $H$.

Complete step by step solution
In the field of physics, the Henry (usually denoted by the image 'H') can be characterized as the unit of electrical inductance. According to the International System of Units (frequently condensed to SI), one henry is equivalent to the self-inductance of a coil through which an electric current flow of size of one ampere is flowing and the resultant flux linkage made by it is equivalent to one weber. The SI unit of electrical inductance is named after the American researcher Joseph Henry (who is additionally credited with the disclosure of electromagnetic acceptance since he found it freely and at around a similar time as the English researcher Michael Faraday). On the other hand, one Henry can be characterized as the inductance of an electrical circuit which changes at the rate of one ampere for every second and the subsequent electromotive force (EMF) over the inductor has a magnitude of one volt.

The one henry is the self inductance of the coil in which the one volt of the electromotive force is produced when the rate of the change of the current in the coil is one ampere per second.

Note The henry is also represented as the ampere per second, it shows that the henry is directly proportional to the current and the henry is inversely proportional to the time. When the current increases, the henry also increases and the time increases, the henry decreases.
