7) The 6 k2 and 10 k2 resistors are connected in series and they are connected across a 20.0-V battery having negligible internal resistance. You use a voltmeter having an internal resistance of 12 k2 to measure the potential difference across the 10 k2 resistor. What is the voltmeter reading in error in percentage from the true potential difference? The true potential difference is without the meter present. a) 0% b) 18.9% c) 23.8% d) 31.3% e) none of above

Question
7) The 6 k2 and 10 k2 resistors are connected in series and they are connected across a 20.0-V battery
having negligible internal resistance. You use a voltmeter having an internal resistance of 12 k2 to
measure the potential difference across the 10 k2 resistor. What is the voltmeter reading in error in
percentage from the true potential difference? The true potential difference is without the meter
present.
a) 0%
b) 18.9%
c) 23.8%
d) 31.3%
e) none of above
