I have a nasty circuit here, and I have been trying to perform a mesh current analysis (as described in the wikipedia article) on it, with little success... I have drawn the curcuit and have put up the equations.
**broken link removed**
The provided values are: R1 = 1kΩ, R2 = 2kΩ, R3 = 3kΩ, Iq1 = 1mA, Iq4 = 4mA, Uq2 = 2V and Uq3 = 3V, I have also noted them in the drawing.
I have some trouble putting up the equations for IM1 and IM2 (currents within Mesh1 and Mesh2). Also, can you please tell me if those few equations I managed to get out of the schematic are correct?

What is nasty about it? You already have the answer just by looking at it. You have a 1 ma current source in the west loop, and a 4 ma current source is the east loop. That gives 4 ma -1 ma = 3 ma in the branch dividing the east and and west loops. What more do you need?
Another question: The assigment asks for the internal resistance of this circuit between A and B. Shouldn't that be zero, due to the constant current source across A and B???

Ah, there we go Now I remember. To calculate the internal resistance, I have to break the connection at every constant current source, and place a short circuit across any voltage source. Is that correct?
