Two batteries with emf &, and &,, with internal resistances r, and r, respectively, are connected as shown in the diagram below. (Assume &, = 12 V and r, = 1 0.) E (a) Calculate the magnitude and indicate the direction of flow of current in the figure shown above. &, = 35.0 V and r, = 0.60 0. magnitude A direction ---Select--- (b) Find the terminal voltage of each battery, V. = V VReferring to the example combining series and parallel circuits and the following figure, calculate I, (in A) in the following two different ways.
