Question

The current in the figure below is 0.54 A. (Let the internal resistance of battery 1 be r1 = 1.4 ?? and the internal resistance of battery 2 be r2 = 1.1 ??.) 6.0 V 9.0 V r1 r2 Battery 1 Battery 2 a b R (a) Find the voltage drop Vab. (b) Find the power dissipated in R. (c) Find the useful electric power supplied by battery 2. (Note: Do not forget the internal resistance of battery 2.) (d) Find the rate at which chemical energy is stored in battery 1. (Note: Do not include power dissipated in the internal resistor of battery 1 in your answer.)
