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 V_A - V_B = 78 V.

(a) Is the device represented by "Box" absorbing or providing energy to the circuit, and

(b) At what rate?
