*** Problem 3 When switch S in Figure 1 is open, the voltmeter V reads 3.08 V. When the switch is closed, the voltmeter reading drops to 2.97 V, and the ammeter reads 1.65 A. (Note: r is internal resistance of the battery.) fr Figure 1: Assume that the two meters are ideal so they don't affect the current in the circuit. a What is the EMF, V, produced by the battery? b) What is the liternal cesistance, r, of...
In the figure a voltmeter of resistance Rv = 480 s2 and an ammeter of resistance RA = 2.03 12 are being used to measure a resistance R in a circuit that also contains Ro = 100 1 and an ideal battery of emf ε = 12.0 V. Resistance R is given by Vli, where V is the potential across R and i is the ammeter reading. The voltmeter reading is V', which is V plus the potential difference across...
