Assume you are a project engineer and one of your
staff is assigned to analyze the circuit shown in
g 24.30. The reference node and node numbers
given on the figure were assigned by the analyst.
Her solution gives the values of v₁ and v2 as 105 V
and 85 V, respectively.
a) What values did the analyst use for the left-most
and right-most node voltages when writing KCL
equations at nodes 1 and 2?
b) Use the values supplied by the analyst to calon
