An air-filled parallel-plate capacitor has a capacitance of 1.2 pF. The separation of the plates is doubled and wax is inserted between them. The new capacitance is 3.1 pF. Find the dielectric constant of the wax

A parallel plate capacitor has an area of A = 94 cm2, a capacitance C = 727 pF, and a separation D = 0.68 mm between the plates. What must the dielectric constant κ of the material be between the plates?

A certain substance has a dielectric constant of 3.8 and a dielectric strength of 25 MV/m. If it is used as the dielectric material in a parallel-plate capacitor, what minimum area should the plates of the capacitor have to obtain a capacitance of 5.3 × 10-2 µ F and to ensure that the capacitor will be able to withstand a potential difference of 3.1 kV?

A 1.00-?F capacitor is charged by being connected across a 9.0-V battery. It is then disconnected from the battery and connected across an uncharged 8.00-?F capacitor. Determine the resulting charge on each capacitor.
