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)
