Hello, I'm trying to simulate a homework problem.

I don't know how to configure the Amp setting for I1 to be 1 - (the voltage across C1).
I also don't know how to configure the Amp setting for I2 to be 2 - 2 x (voltage across C1)

I tried using an equation but I'm getting errors.

Can anyone give me some help please.

Thanks

 

V(C1) is not a valid expression since C1 is not a circuit node.
You need to label (Label Net) the C1 node.

Hello, thank you for responding to my message. Do you mean like this:

 

I changed the Current Source with a Behavioral Current source and was able to run a sim.


Now I'm trying to get the simulation to show the current and voltage across the C1 cap.

 

I'm trying to simulate a homework problem.

Post that problem.

Below is the correct (I think) simulation of your original circuit:

The inductor, being in series with an ideal current source, has no effect on capacitor current or voltage.

Note the uic (not startup) transient simulation command for proper initial conditions at startup.

Show the image and text of the problem the instructor gave you.

Thank you very much.
I will will calculate I(C1) and V(C1) by hand.
Have a great day
