PROCEDURE 1. Consider the dual supply circuit of Figure 7.1 using El = 6 volts, E2 = 12 volts, R1 =- R2 = 6.8 k, R3 = 10 k, R4 = 22 k and R5 = 33 k. This circuit will require three loop describe fully. This means that there will be three mesh currents in spite of the fact there are five branch currents. The three mesh currents correspond to the curn through R1, R2, and R4. 2. Using KVL, write the loop expressions for these loops and then solve to find the n currents. Note that the voltages at nodes A and B can be determined using the n currents and Ohm's Law. Compute these values and record them in Table 7.1. 3. Build the circuit of Figure 7.1 using the values specified in step four. Measure the t mesh currents and the voltages at node A, node B, and from node A to B, and recor Table 7.1. Be sure to note the directions and polarities. Finally, determine and record deviations in Table 7.1. SIMULATION Build the circuit of Figure 7.1 in a simulator. Using the DC Operating Point simulation func determine the currents at each resistor, and compare these to the theoretical and meast values recorded in Table 7,1.

GRAPH AND DESCRIBE

PROCEDURE
1. Consider the dual supply circuit of Figure 7.1 using E1 = 6 volts, E2 = 12 volts, R1 = 4.7k,
R2 = 6.8 k, R3 = 10 k, R4 = 22 k and R5 = 33 k. This circuit will require three loops to
describe fully. This means that there will be three mesh currents in spite of the fact that
there are five branch currents. The three mesh currents correspond to the currents
through R1, R2, and R4.
2. Using KVL, write the loop expressions for these loops and then solve to find the mesh
currents. Note that the voltages at nodes A and B can be determined using the mesh
currents and Ohm's Law. Compute these values and record them in Table 7.1.
3. Build the circuit of Figure 7.1 using the values specified in step four. Measure the three
mesh currents and the voltages at node A, node B, and from node A to B, and record in
Table 7.1. Be sure to note the directions and polarities. Finally, determine and record the
deviations in Table 7.1.
SIMULATION
Build the circuit of Figure 7.1 in a simulator. Using the DC Operating Point simulation function,
determine the currents at each resistor, and compare these to the theoretical and measured
values recorded in Table 7.1.
