A Current Controlled Voltage Source (CCVS), where the voltage drop is controlled by the current through the CCVS element itself, acts just like a resistor. This can be created using a behavioral expression referencing the voltage source's own current.


This example is from the Dependent (Controlled) Sources chapter of Ultimate Electronics Book. It shows a DC Sweep simulation showing that a self-connected CCVS acts just like a resistor.

This takes advantage of CircuitLab's support for Behavioral Sources, where you can define a voltage or current source's value with a simple mathematical expression.

In this case, a voltage source element V2 is defined as having a current that is 100 * I(), i.e. its own current I() multiplied by some gain. The result acts like a resistor.
