In the figure battery 1 has emf 81= 14.0 V and internal resistance r = 0.040 Q and battery 2 has emf 82= 14.0 V and internal resistance r2 = %3D 0.018 Q. The batteries are connected in series with an external resistance R. (a) What R value makes the terminal-to-terminal potential difference of one of the batteries zero? (b) Which battery is that? E2 Units (a) Number (b) battery 1
