    Between the plates is filled with a dielectric material of relative permittivity εr. The area of each plate is A, and the separation between the plates is d. The capacitance of the capacitor is given by the formula:

    C = (ε0 * εr * A) / d

    where C is the capacitance, ε0 is the vacuum permittivity (8.85 x 10^-12 F/m), εr is the relative permittivity, A is the area of each plate, and d is the separation between the plates.

    The capacitance of a parallel plate capacitor increases when the relative permittivity of the dielectric material increases. This is because the relative permittivity is a measure of how much the dielectric material can store electric charge per unit volume compared to vacuum. A higher relative permittivity means that the dielectric material can store more charge, leading to a higher capacitance.

    Similarly, the capacitance of a parallel plate capacitor increases with an increase in the area of each plate. This is because a larger plate area provides more surface area for charge to accumulate, resulting in a higher capacitance.

    On the other hand, the capacitance of a parallel plate capacitor decreases with an increase in the separation between the plates. This is because a larger separation reduces the electric field between the plates, reducing the amount of charge that can be stored, resulting in a lower capacitance.

    In summary, the capacitance of a large parallel plate capacitor is directly proportional to the relative permittivity and the area of each plate, and inversely proportional to the separation between the plates.

    If voltage source is removed then in both cases charge Q is constant.
    Case-1: (Q1, = Q; V1 = V)
    Q1 = C1 V1
                                                            ...(i)
    Case-2: (Q2 = Q; V2)
    Q2 = C2V2
                                                                ...(ii)
    Equation (i) is equal to equation (ii)
             ...(iii)
