A circuit consists of a series combination of 6.50 −kΩ and 4.50 −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 4.50 −kΩ resistor using a voltmeter having an internal resistance of 10.0 kΩ.
Part A: What potential difference does the voltmeter measure across the 4.50 kohm resistor?
PartB:What is the true potential difference across the resistor when the meter is not present?
Part C: By what percentage is the voltmeter reading in error from the true potential difference?
