Question

b) A linear resistance potentiometer is 50mm long and is uniformly wound with wire having a resistance of 10000?. Under normal conditions, the slider is at the center of the potentiometer. Find the linear displacement when the resistance of the potentiometer as measured by a Wheatstone bridge for two cases is; (i) 3800? (ii) 7500? Are the two displacements in the same direction? If it is possible to measure value of a 10? resistance with the above arrangements, find the resolution of the potentiometer in mm.

Step 1

The potentiometer is a linear device, meaning the resistance varies linearly with the position of the slider along its length. The total resistance of the potentiometer is 10,000Ω, and its total length is 50mm. The slider, when at the center, divides the Show more…
