polarity? happen to the mesh currents if the positions of E1 and R1 in Fiaure 61 ver swapped? 3. If branch current analysis (BCA) was applied to the circuit of Figure 6.2, how many unknown currents would have to be analyzed nd how many equations would be needed? How does this compare to mesh analysis? unknown currents 3 loof equations E 2 nodal equations In mesh analysis, 3 loop equations would be required 4. The circuits of Figures 6.1-and 6.2 had been analyzed previously in the Superposition Theorem exercise. How do the results of this exercise compare to Ihe earlier results? Should the resulting curents and voltages be identical? If not, what sort of things might affect the outcome? upply circuit of Figure 131 ucing El = 10 volts.
