There's only one unknown -- the voltage V1. Call the bottom rail ground, then you only have to solve for V1 to know all the voltages and currents in the circuit. The V2 is just -10V, set by the voltage source on the right.lostinhere said:I have this much
Node 1: between the 25k resistor and the 11mA source)
node 2: between the 500 ohm resitor, 10v source, 1k resistor and 500 resistor and the 11mA source
V1: voltage across the 250 resistor
V2: voltage arcross the 1k resistor
reference node at the bottom of the pic
node1: (V1-20)/25K+V1/250+.011+(V1-V2)/500=0
node2: -.011+V2/1000+(V1-V2)/500+...=0
I'm not quite sure how to hande the 10v supply.
