Question

What is the order of minimum displacement that can be measured with a capacitive transducer?

• A. 1 cm
• B. 1 mm
• C. 1 $\mu$m
• D. $1 \times 10^{-8}$ m

Hint:

Capacitive transducers can measure extremely small displacements, often in the range of nanometers or lower, making them ideal for precision measurements.

Answer 1

The Correct Option is D

Capacitive transducers are highly sensitive devices that can measure very small changes in displacement. The order of displacement that a capacitive transducer can measure typically falls within the range of nanometers ($1 \times 10^{-9}$ m) to micrometers ($1 \times 10^{-6}$ m). However, advanced capacitive sensors can measure displacements in the range of picometers to nanometers.
In this case, the correct answer is $1 \times 10^{-8}$ m, which is within the detectable range for highly sensitive capacitive transducers.
