Consider the dual supply circuit of Figure 13.2 using E1 = 10
volts, E2 = 15 volts, R1 = 4.7 k, 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.
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 13.2.
