Two identical batteries of emf 'g = 12.0 V and internal
Chapter 27, Problem 40(choose chapter or problem)
Two identical batteries of emf 'g = 12.0 V and internal resistance I' = 0.200 il are to be connected to an external resistance R, either in parallel (Fig. 27-50) or in series (Fig. 27-51). If R = 2.001', what is the current i in the external resistance in the (a) parallel and (b) series arrangements? (c) For which arrangement is i greater? If R = 1'/2.00, what is i in the external resistance in the (d) parallel and (e) series arrangements? (f) For which arrangement is i greater now?
