On increasing the distance between the plates of a variable capacitor,

1.	On increasing the distance between the plates of a variable capacitor, the displacement- capacitance characteristics changes _______(a) proportionally(b) linearly(c) exceptionally(d) hyperbolicallyI have been asked this question in an online interview.Origin of the question is Displacement, Position and Motion Transducers in portion Physiological Transducers of Biomedical Instrumentation
Answer» The CORRECT CHOICE is (d) hyperbolically The explanation: By moving ONE plate of the capacitor with respect to the other, the capacitance will vary inversely with respect to the plate separation. This will give a hyperbolic displacement capacitance characteristic. This is how variable capacitance is EMPLOYED as displacement transducers.
