When Switch S In The Figure Figure 1 Is Open The Voltmeter V Of The Battery Reads 3 07 V When The Switch Is Closed Th 1 (27.33 KiB) Viewed 36 times

a) Find the emf
b) Find the internal resistance of the battery
c) Find the Circuit resistance
When switch S in the figure (Figure 1)is open, the voltmeter V of the battery reads 3.07 V When the switch is closed, the voltmeter reading drops to 2.92 V, and the ammeter A reads 1.68 A Assume that the two meters are ideal, so they don't affect the circuit. Figure 1 of 1 V r E WE R w A S
