Read the notes in this lab and find the nodal voltages Va, Vb, Vc and the source current IS in the circuit of Figure 52, and record your calculations in Table 1.
You might find it convenient to use series and parallel transformations, starting from the right side of the circuit.To start off, R5 and R6 are in series, with a total resistance of 2.7+3.3 = 6.0 k; this resistance is in parallel with R4, with equivalent resistance
Keeping going like this to simplify the circuit and determine IS. Now work the other way and determine the nodal voltages.
