S estion 15 ked out of 36 Flag question The output voltage Vout of a potentiometer sensor is measured by means of the system that is shown in the picture, where the voltmeter has a range of 10 V and an absolute uncertainty expressed as &V= (0.5% - reading +0.2%-range) V -- X (mm) 4 100- Applied Electronics and Measurements ho Rx V V out The input/output relationship of the sensor is: Rx = X-KR. where K-001 (mm) (negligible uncertainty) The resistor R = 10 k (negligible uncertainty), while the voltage V5.05 V (measured with the same voltmeter that measures V Evaluate nominal value and absolute uncertainty of the position X, of the potentiometer when the measured output voltage is V2.85 V The load effect of the voltmeter is negligible O (a) X = 56.4 mm, 6X = 1.2 mm O (b)X =230 mm: 6X = 1.2 mm (c) X = 56 mm: 6X = 12 mm O (d) X = 56.40 mm, 6X = 0.12 mm
