Figure 25.16 shows a source (a battery) with emf & = 12 V and internal resistance r = 2 N. (For comparison, the internal resist- ance of a commercial 12-V lead storage battery is only a few thou- sandths of an ohm.) The wires to the left of a and to the right of the ammeter A are not connected to anything. Determine the respec- tive readings Vab and I of the idealized voltmeter V and the ideal- ized ammeter A. A source of emf in an open circuit. V a r = 20, ε = 12 V A
