MULTISIM need help with placing current dependent current source?

[IMG]http://i56.tinypic.com/ei7a0n.png[/IMG]

 

as you can see it is a current dependent current source and has value 2*I(x). i have placed it in a circuit in multisim but i have a feeling i'm doing it wrong:

and don't worry about the 25-amp resistor at the right it was the load resistor we had to place.

Hello,

 

Well from the first circuit you have there, you are looking for the current source to output 2x curret passing between the 10ohm resistor and the 19v source. So you need to connect that line to the current controller (the square thing attached to the current source), basically running a wire from the voltage source to one end of the controller, then running the other end of the controller to the 10ohm resistor (deleting the connection between the resistor and the source so that they only connect through the controler).

Hi,

 

The main problem I see is that there is no ground in this circuit. You need to have a ground for simulation to run properly. Attach it to the net connecting to the negative terminal of the power source.

 

Hope this helps.
