Parallel plate capacitors, Solid sphere and Concentric spherical shell capacitor

Parallel Plate Capacitors with and without Dielectric

Parallel Plate Capacitor||Spherical and Cylindrical Capacitor

You have a parallel plate capacitor, a spherical capacitor and a cylindrical capacitor. Each capacitor is charged and then removed from the same battery. Consider the following situations : I:· Separation between the plates of parallel plate capacitor is reduced II: Radius of the outer spherical shell of the spherical capacitor is increased Ill: Radius of the outer cylinder of cylindrical capacitor is increased. Which of the following is correct?

In a parallel plate capacitor, the capacitance

A sheet of copper is inserted in the air gap of a parallel plate capacitor, without touching any of the two plates of the capacitor. The capacitance of the capacitor is

In the reported figure, a capacitor is formed by placing a compound dielectric between the plates of parallel plate capacitor. The expression for the capacity of the said capacitor will be : (Given area of plate = A)

A parallel plate capacitor is charged and then isolated. On increasing the plate separation
