Question

Define the unit of self-inductance.

Answer 1

Self-Inductance:

1. The quality of a current-carrying coil that opposes the change in current passing through it is called self-inductance.
2. By Faraday's law, $e=-L\frac{dI}{dt}$. Where e is emf, L is inductance and I is current.
3. The unit of inductance is Henry.
4. The amount of inductance necessary to create an emf of $1$ volt in a conductor when the current changes at a rate of $1$ ampere per second is defined as one Henry.
