Capacitor with Variable Capacity: Gang Capacitor

Five 1-in^2 plates are arranged in attached file (Plates.jpg). The plate spacings are 0.01 in. The arrangement is to be used for a displacement transducer by observing the change in capacitance with the distance x. Calculate the sensitivity of the device in pico-farads per inch. Assume that the plates are separated by air.


Solution Summary

Practically used in tuning circuits.
