Description

An ideal linear conductor: the current through it is proportional to the voltage across it. It is a resistor specified by conductance, which allows G = 0 (an open circuit).

Example

RC and RL transients A 10 V step charges a capacitor through a resistor, and another builds current in an inductor through a conductor.

Ports

Conserving terminals 2

  • +pelectrical

    Positive pin. Current into p is counted as positive.

  • −nelectrical

    Negative pin.

Parameters

  • ConductanceG1 S

    ≥ 0

    Conductance, in siemens. 0 or more; 0 makes the block an open circuit.

Equations
