Two electric circuits, represented by boxes A and B, are connected as shown in the figure below. The reference direction for the current i in the interconnection and the reference polarity for the voltage v across each interconnect are shown. For each of the following sets of values, calculate the power in the interconnection and state whether the power is flowing from A to B or vice versa. Part (A) i = 6 A, v = 30 V Part (B) i = −8 A, v = −20 V Part (C) i = 4 A, v = −60 V Part (D) i = −9 A, v = 40 V

Question 2

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

Part (A) i = 6 A, v = 30 V

Part (B) i = −8 A, v = −20 V

Part (C)  i = 4 A, v = −60 V

Part (D) i = −9 A, v = 40 V
