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?

Although an ideal voltmeter has an infinite
internal resistance, this theoretical ideal is usually not met in
practice. The voltmeter in the Figure has an internal resistance of
7 x 109 Ω and is used to measure the voltage across the
resistor R2 as shown. Attaching this non-ideal voltmeter
decreases the voltage across R2. Calculate the magnitude
of this decrease using an emf of 16 V and R1 =
R2 = 200 kΩ.
