A parallel plate capacitor with only air between the plates has a capacitance of 8pF . What will be the capacitance if the distance between the plates is reduced by half and the space between them is filled with a substance of dielectric constant 6?

How does electrical capacitance of a parallel plate capacitor depend on the distance between the plates ?

In a parallel plate capacitor with air between the plates, each plate has an area of 6xx10^(-3)m^2 and the distance between the plates is 3 m. Calculate the capacitance of the capacitor. If this capacitor is connected to a 100V supply. What is the charge on the each plate of the capacitor?

An air filled parallel plate condenser has a capacity of 2 pF. The separation of the plates is doubled and the interspace between the plates is filled with wax. If the capacity is increased to 6 pF, the dielectric constant of wax is

A parallel plate capacitor with air as the dielectric has capacitance C.A slab of dielectric constant K and having the same thickness as the separation between the plates is introduced so as to fill one-fourth of the capacitor as shown in the figure.The new capacitance will be
