Conductor

Ideal linear electrical conductor relating current and voltage through its conductance.

This component models an ideal electrical conductor where the electrical current flowing through it is directly proportional to the voltage difference across its terminals. The relationship is defined by Ohm's law:

$$i=Gv$$

where i is the current, v is the voltage, and G is the conductance. The conductance G is a parameter, representing the ease with which current flows through the material, and is the reciprocal of resistance. This model assumes linear behavior, meaning the conductance G remains constant regardless of the voltage or current. It inherits from TwoPin, implying it has two electrical connection points (pins) where voltage v is measured across and current i flows through.

This component extends from OnePort
