Nodal analysis with parallel resistors

eurekameh · Mar 6, 2012

Circuit schematic labeled Figure 5.71 with a 4.2 V source, resistors of 1.8 kΩ, 2.5 kΩ, 2.3 kΩ, 2.5 kΩ and 1.1 kΩ, and output terminals marked Voc.

I'm trying to determine v,oc using nodal analysis. I have labeled the two node voltages at the top v,1 and v,2. When doing the KCL equation for node voltage 2, I run into the 1.1 kohm and 2.3 kohm parallel combination. Is it valid if I just combine these parallel resistors into one resistor?
