A potentiometric displacement transducer with a uniform resistance per unit length of track has a resistance of 10 kn and track length of 290 mm and used with the output voltage being measured with an instrument of internal resistance 20 kN as shown in Figure 1.1 below. The potentiometer is connected to a 5 V d.c. source of negligible internal resistance. V. m Õmõnad Figure 1.1: Potentiometric Displacement Transducer If the output voltage is measured as 1.25 V.
