Question

What is Henry?

Answer 1

Inductance:

1. The henry (H) is an electrical inductance measurement unit.
2. It is named after the American scientist Joseph Henry.
3. According to the SI, $1\mathrm{henry}$ is equivalent to the self-inductance of a coil throughout which an electric current of size $1\mathrm{ampere}$ flows, as well as the associated flux connectivity equivalent to $1\mathrm{weber}$.

Mathematically,

$\mathrm{L}=\frac{\mathrm{\varphi }\left(\mathrm{i}\right)}{\mathrm{i}}$

Here,

$\mathrm{L}$ is the inductance.

$\mathrm{\varphi }\left(\mathrm{i}\right)$ is the magnetic flux of current.

$\mathrm{i}$ is the current.

Therefore, henry is the SI unit of electrical inductance.
