A parallel-plate capacitor has capacitance C. A second parallel-plate capacitor has plates with twice the area and half the separation. The capacitance of this second capacitor is most nearly
A parallel-plate capacitor was used in connection with an impedance analyser and a cryostat. The errors caused by the cables needed between analyser and cooled capacitor were minimized. Field homogenization within the measuring space is realized by correcting the reference potential at the guard ring...
