The circuit shown in Fig. E25.30 contains two batteries, each with an emf and an internal resistance, and two resistors. Find (a) the current in the circuit (magnitude and direction); (b) the terminal voltage V_a_b of the 16.0-V battery; (c) the potential difference V_a_c of point a with respect to point c. (d) Using Fig. 25.20 as a model, graph the potential rises and drops in this circuit.
