`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.

Usage

Inductor(L)

Parameters:

Name	Description	Units	Default value
`L`	Inductance value of the component in Henries (H)	H

Connectors

p - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)
n - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)

Variables

Name	Description	Units
`v`	Voltage across the component (between pin p and pin n).	V
`i`	Current flowing through the component (from pin p to pin n).	A

Behavior

\[ \begin{align} v\left( t \right) &= \mathtt{p.v}\left( t \right) - \mathtt{n.v}\left( t \right) \\ i\left( t \right) &= \mathtt{p.i}\left( t \right) \\ \mathtt{n.i}\left( t \right) + \mathtt{p.i}\left( t \right) &= 0 \\ L \frac{\mathrm{d} i\left( t \right)}{\mathrm{d}t} &= v\left( t \right) \end{align} \]
