Quick question that is throwing me off....(adsbygoogle = window.adsbygoogle || []).push({});

If you have a dependant current source in a parallel circuit, how do you represent that in your KCL equation? The one in this problem is Vo/2000.

I took that as I=V/R so R=2000. Since it is in a parallel circuit on its own 'branch' I used Vs/2000. But when I plug it all into the equations, the answer is wrong.

The circuit is this....

Parallel circuit with 4 branches. The following are the branches from left to right.

1. Dep. Current Source = Vo/2000

2. 6k ohm resister with + on top. (Marked also with Vs).

3. 1k ohm resister and a 2k ohm resister. Vo is indicated across the 2k ohm. The + sign is between the two resisters and the - is at the bottom of the 2k ohm.

4. indep current source at 2mA.

I took Vs to be the voltage across each branch since they are all in parallel and it is stated that Vs is across the 6k ohm resister. I tried to do the....

Vs/2000 + Vs/6k + Vs/3k + 2mA = 0

and then solved for Vs which ended up being 2V. Then used that to find Vo... except it is way off as the answer says Vo is 8V.

So, I am either screwing up the representation of the Vo/2000 in the equation or I am screwing up the entire KCL for the equation.

If someone could give a hint, Id appreciate it.
