Open in App
Solution

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, 1henry is equivalent to the self-inductance of a coil throughout which an electric current of size 1ampere flows, as well as the associated flux connectivity equivalent to 1weber.

Mathematically,

L=ϕ(i)i

Here,

L is the inductance.

ϕ(i) is the magnetic flux of current.

i is the current.

Therefore, henry is the SI unit of electrical inductance.
