일반물리학 2 — Current and Resistance: Problem 28

28 The current through the battery and resistors 1 and 2 in Fig. 26-24a is 1.50 A. Energy is transferred from the current to thermal energy \(E_{th}\) in both resistors. Curves 1 and 2 in Fig. 26-24b give that thermal energy \(E_{th}\) for resistors 1 and 2, respectively, as a function of time \(t\). The vertical scale is set by \(E_{th,s} = 40.0 \text{ mJ}\), and the horizontal scale is set by \(t_s = 5.00 \text{ s}\). What is the power of the battery?
