A circuit consists of a series combination of 6.00-kΩ and 5.00-kΩ resistors connected across a 50.0-V battery having negligible internal resistance. You want to measure the true potential difference (that is, the potential difference without the meter present) across the 5.00-kΩresistor using a voltmeter having an internal resistance of 10.0 kΩ. You may want to review (Pages 858 - 862) . For related problemsolving tips and strategies, you may want to view a Video Solution of Measuring resistance. Part A...

When you connect a standalone battery to a voltmeter the voltmeter reads 5 V. (a) Assuming the voltmeter has a very high resistance, what is the approximate elec- tromotive force in the battery? (b) When you hook the same battery up to a circuit with a 15 Ohm resistor, you hook up the voltmeter to read the terminal voltage across the battery and it now reads 4.688 V instead of 5 V. What is the internal resistance of the battery?
