Procedure:
1.Set up nodal equations for the circuit in Figure 3.1 and show the steps of your calculations in a separate piece of paper and paste it at the end of your lab report. Use MATLAB to solve for the node voltages. Record the calculated values in Table 3-1.
Construct the circuit using the bench power supply and other supplied parts. Make sure that the circuit is properly grounded. If you run out of banana-to-clip lead, use jumper wire to establish the ground connection.
Measure the node voltages using the DMM, and record the measurement in Table 3-1.

- With the measured node voltages, determine the voltage across and current through each resistor. Record the results (only the magnitude the currents and voltages) in Table 3-2. Label the direction of the resistor currents in Figure 3.1.
