일반물리학 2 — Circuits: Problem 61

61 In Fig. 27-57, the ideal batteries have emfs \(\mathcal{E}_1 = 12\text{ V}\) and \(\mathcal{E}_2 = 4.0\text{ V}\). What are (a) the current, the dissipation rate in (b) resistor 1 (\(4.0\ \Omega\)) and (c) resistor 2 (\(8.0\ \Omega\)), and the energy transfer rate in (d) battery 1 and (e) battery 2? Is energy being supplied or absorbed by (f) battery 1 and (g) battery 2?
