Struct Capacitor 

pub struct Capacitor { /* private fields */ }

Capacitor component with voltage memory.

Uses backward Euler companion model:

• Equivalent conductance: G = C / dt
• Equivalent current source: J = G * V_previous

Implementations

impl Capacitor

pub fn new(n1: i32, n2: i32, capacitance: f32) -> Self

Create a new capacitor between two nodes.

Arguments

• n1, n2 - Node indices (0 = ground)
• capacitance - Capacitance in Farads

Trait Implementations

impl Component for Capacitor

fn nodes(&self) -> (i32, i32)

Get the node indices this component connects (node_a, node_b). Node 0 represents ground.

fn get_conductance(&self, dt: f32) -> f32

Return the equivalent conductance for the static Y matrix. Called once during preprocessing.

fn get_current_source(&self, dt: f32) -> f32

Return the equivalent current source for the dynamic J vector. Called every sample for reactive components.

fn update_state(&mut self, v_a: f32, v_b: f32, _dt: f32)

Update internal state after solving node voltages. Called every sample for reactive components to store history.
