In Fig. 26-22a, a `15Omega` resister is connected to a battery. Figure 26-22b shows the increase of thermal energy `E_(th)` in the resistor as a function of time t. The vertical scale is set by `E_(th.s) = 2.50 mJ,` and the herizontal scale is set by `t_(s)= 4.0s`. What is the electric potential across the battery?
