1. Charge separation in a parallel-plate capacitor causes an internal electric field. 2. A simple parallel plate capacitor has two conductors separated by a dielectric layer. 3. A parallel plate capacitor is not a good choice for such a sensor pattern. 4. The capacitance formula for plate capacitors is: 5. Thus, the standard formula for conventional plate capacitors can be used to calculate their capacitance: 6. Note that the electric field can be created by placing a parallel plate capacitor across the crystal. 7. Darlington s procedure starts by considering the field between the two plates of a parallel plate capacitor . 8. The capacitance of the plates is inversely proportional to the distance between them for a parallel-plate capacitor . 9. In the experiment, a suspended parallel-plate capacitor is held by a fine torsion fiber and is charged. 10. As a consequence the HBV has electrical properties resembling the parallel plate capacitor with a voltage dependent plate distance d.
