The current in the figure below is0.62A. (Let the internal resistance of battery 1 be

r₁=1.4

and the internal resistance of battery 2 be

r₂=1.2.)

(a) Find the voltage dropV_ab. (b) Find the power dissipated inR. (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.)
