WebKirchhoff's second rule requires emf−Ir−IR 1 −IR 2 =0. Rearranged, this is emf=Ir+IR 1 +IR 2, meaning that the emf equals the sum of the IR (voltage) drops in the loop. The emf supplies 18 V, which is reduced to zero by the resistances, with 1 V across the internal resistance, and 12 V and 5 V across the two load resistances, for a total of 18 V.
