In both schematics you have two sources (isource and vsource) in series. I wondered why this worked with the second at all... Just a simple consideration: the voltage-source forces 12V amp at 5k Ohm resistor -> I = V/R = 2.4mA. At the same time you force 1mA by the isource... So this is a physical contradiction. Same goes for the first one. So my suggestion: 1. Leave the current sources. 2. Put somewhere a ground symbol where you want to have zero volt! Hope this helps, Stefan. |
