(a) An ideal voltmeter is connected between b and c; it reads V c- V b = 12 V. What is the EMF of the battery? (b) What resistance would an ohmmeter connected across points a and c read? (c) An ideal ammeter is inserted between points a and b it reads 0.18 A. Determine the internal resistance of the battery? (d) What does the voltmeter connected across b and c read now? (e) Calculate the magnitude of the current through R 2 . (f) At what rate is thermal energy (heat) being produced inside the battery? (g) What is the power being provided by the battery to the external circuit (outside the battery)?...
