Current Dependant Modelling
A component's resistance or Voltage may vary due to the level of current passing
through it, or a related part of the Circuit.
The best example of this is a diode, whose forward biased resistance
at room temperature is equal to 0.025 divided by the current flowing through it.
To define your own current dependancy specifications, use this format
when designating a value to a component.

Variable I = Current flowing through this device
or fixed T = Current flowing perpendicular to this device
Link = Current flowing through the two
specified nodes
note: A node is a section of a circuit that is composed entirely of wires. They are labeled alphebetically from top left to bottom-right
Virtual nodes are introduced directly above or to the left of any component in parellel with another.
Virtual nodes are labeled from top-left to bottom-right alphabetically starting from the label of the last actual node.
The number of nodes must be kept to a minimum for quick and accurate analysis
note: The symbol T is used primarily BJT modelling and is not reccomended for other devices
note: If the / symbol is used and current drops to 0 or below the resistance becomes infinity.
