Two electric circuits, represented by boxes A and B, are connected as shown in Fig. P1.13. The reference direction for the current I in the interconnection and the reference polarity for the voltage v across the interconnection are as shown in the figure. For each of the following sets of numerical values, calculate the power in the interconnection and state whether the power is flowing from A to B or vice versa.
