### Hint for Ch. 28, 44P

Notice that by symmetry in the parallel configuration, the identical batteries must have identical currents.
So the current in each battery is exactly one-half of the current in the load resistor.
In the series configuration, a quick application of the loop rule should convince you that an effective resistance of all three resistors in series and an effective emf of the sum of the two is acceptable.
