This is a question from which book?16\ The output voltage from a translational motion potentiometer of stroke length

0.1m

is to be measured by an instrument whose resistance is

10k\\\\Omega

. The maximum measurement error, which occurs when the slider is positioned three-fourth of the way along the element (i.e., when

x_(-)i=3x_(-)(t)/(4)

in the figure, must not exceed

2%

of the full-scale reading. The highest possible measurement sensitivity is also required. A family of potentiometers having a power rating of

1W

per

0.01m

and resistances ranging from

100\\\\Omega

to

10k\\\\Omega

in

100\\\\Omega

steps are available. Choose the most suitable potentiometer (in

\\\\Omega

) from this range and calculate the sensitivity of measurement (in V/m) that it gives. Enter values of

R_(-)t

and measurement sensitivity in the same order.\ (3 Points)
