Multiple Choice
You want to determine the resistance R of a resistor by passing a current I through it,measuring this current with an ammeter connected in series with the resistor,measuring the voltage V across only the resistor with a voltmeter,and then dividing the voltage by the current to get the resistance.If the voltmeter has an internal resistance of 5.0 k ,what is the percentage error (relative to the true value) in measuring a 1.0-k resistance?
A) 0.17%
B) 1.7%
C) 2.0%
D) 17%
E) 20%
