일반물리학 2 — Circuits: Problem 11

11 In Fig. 27-25, the ideal batteries have emfs \(\mathcal{E}_1 = 5.0 \text{ V}\) and \(\mathcal{E}_2 = 19 \text{ V}\), the resistances are each \(2.0 \text{ }\Omega\), and the potential is defined to be zero at the grounded point of the circuit. What are potentials (a) \(V_1\) and (b) \(V_2\) at the indicated points? (c) What is the power of battery 2?
