Question:
Figure shows a section of a circuit. The resistances are R1 = 2.0?, R2 = 4.0?, and R3 = 6.0?, and the indicated current is i = 6.0 A. The electric potential difference between points A and B that connect the section to the rest of the circuit is VA - VB = 78 V.
(a) Is the device represented by "Box" absorbing or providing energy to the circuit, and
(b) At what rate?
