Help with Multisim (Adding a dependent voltage source that uses a resistor as Vx

[Smashbrohammer]

I am fairly new to Multisim so please excuse my newbness 🙂

Anyways, it is a basic circuit.  There is a R1 and R2 resistor with other random components.  But I want to add a Dependent Voltage Source which multisim calls ABM voltage source.  How do I set it up to where it is like 3 * R2 = the dependent voltage source in multisim?

I can't seem to get the ABM to link with anything.  I don't even know how to start.

This is not a LabVIEW question. I try to have it moved to the multisim board.

You posted in the LabVIEW Board.  You might get more help in the Circuit Design Suite Board.

I do not have Multisim, but in Spice 3 the Non-linear Dependent Source Bxxx can be used.  The voltage (or current) of the source is determiend by an expression.  The expression can include node voltages, branch currents, mathematical functions, and constants.  If you can assure that the current through R2 is never zero, then V = 3*(v(1) - v(2))/current through R2, where 1 and 2 are the nodes connected to R2.  One way to get the current through R2 is to put a zero volt source Vr2 in series with the resistor.  Then i(Vr2) is that current.
