Question:
Suppose that the phasor voltage across ZB, with polarity as indicated in Fig. 9-13, is sought. Choosing meshes as in Fig. 9-12 would entail solving for both I1 and I2, then obtaining the voltage as VB = (I2 − I1)ZB. In Fig. 9-13 three loops (two of which are meshes) are chosen so as to make I1 the only current in ZB. Furthermore, the direction of I1 is chosen such that VB = I1ZB . The matrix equation is set up:
