Conductor

Symbol

Information

An ideal linear electrical conductor is an electrical component that allows current to flow with a defined conductance (G). Conductance is the reciprocal of resistance and determines how easily current flows through the conductor.

The relationship between voltage (V) and current (I) is defined by Ohm’s Law:

\[I = G \cdot V\]

Where:

\(I\) is the current through the conductor (Amperes)
\(G\) is the conductance (Siemens, S)
\(V\) is the voltage across the conductor (Volts)

In practical circuits, conductors with high conductance (low resistance) are used to connect electrical components efficiently.

Ports

p: First terminal of the conductor
n: Second terminal of the conductor

Model

The Conductor model implements an ideal linear conductor with a specified conductance.

The current through the conductor is directly proportional to the voltage applied, following Ohm’s law: I = G * V.

Attributes:

V (signal): Voltage signal across the conductor, defined between nodes (p, n).

I (signal): Current signal through the conductor, defined between nodes (p, n).

G (param): Conductance value in Siemens (S), default is 1.0 S.

Methods:

analog(): Defines the current-voltage relationship:

\[I = G \cdot V\]

Command syntax

The syntax for defining a Conductor in a PyAMS simulation:

# Import the model
from pyams.models import Conductor

# Cname: is the name of the Conductor instance
# p, n: The connection points in the circuit
Cname = Conductor(p, n)
