The plates of an empty parallel-plate capacitor of capacitance 5 pF are 2.2 mm apart. What is the area of each plate?

Two parallel plates having equal and opposite charges with area L x L separation d is filled with a dielectric material as shown in the Figure. The related dielectric constant varies with zask=a+ Here, a 46 cm, b -92 cm, d 0.31 cm and L=1m are given. Find the capacitance of this capacitor in 10-11 Farad. Take o=10-¹¹ C²/Nm². Answer:

What is the capacitance of a capacitor that stores 2.6 μC of charge on its plates when a voltage of 6.6 V is applied between them?

A parallel plate capacitor has capacitance of 230 pF. If the area of the each plate is 60 cm2 and there is a dielectric of κ = 5 between the plates, what is the distance (in mm) between the plates?

An air filled capacitor C= 10uF is connected to a 15V battery. The capacitor is disconnected from the battery and the distance between the plates is doubled. What is the energy stored in the capacitor now?

A parallel plate capacitor has a capacitance of 0.20 μF. The capacitor is notconnected to a battery or a power supply. There is a charge of 24 μC on thecapacitor. How much work must be done on the capacitor to double the separation between the plates?

The plates of a parallel plate capacitor are seperated by 5 mm.  The plate area is 2 m2.  If a potential difference of 10,000 volts is applied across the plates, how much charge will be stored in the capacitor?
