Question #178113

A capacitive level sensor has the dimensions and properties shown below. What is the capacitance C in picofarads at the liquid level shown? Type in a one-decimal number

H = 4.0 meters

h = 3.9 meters

a = 1.0 millimeters

b = 6.0 millimeters

ε = 8.8542 x 10 picofarads/meter

k = 78.5

Expert's answer

Since no image is attached, we can only guess that *H* and *h* are the dimensions of the plates, assume *a* is the plate separation, and *k* is the dielectric constant of the liquid. If *b* is the level of liquid, we have a configuration of two capacitors connected in parallel with the equivalent capacitance
