Analog.Basic.Inductor

Ideal inductor characterized by its inductance L.

This component models a linear inductor, a fundamental passive two-terminal electrical component. It defines the relationship between voltage v and current i based on its inductance L. The behavior is described by the equation:

$$v=L\frac{di}{dt}$$

math where v is the voltage across the inductor (difference between pin p and pin n), i is the current flowing through the inductor (from pin p to pin n), and L is its inductance.

This component extends from ElectricalComponents.Analog.Interfaces.OnePort

Ideal inductor characterized by its inductance L.

This component models a linear inductor, a fundamental passive two-terminal electrical component.
It defines the relationship between voltage `v` and current `i` based on its inductance `L`.
The behavior is described by the equation:
```math
v = L \frac{di}{dt}
```math
where `v` is the voltage across the inductor (difference between pin `p` and pin `n`), `i` is the current flowing through the inductor (from pin `p` to pin `n`), and `L` is its inductance.
