A metal foil of negligible thickness is introduced between the two plates of a capacitor at the centre. The capacitance of capacitor will be

If a thin metal foil of same area is placed between the two plates of a parallel plate capacitor of capacitance C, then new capacitance will be

A metal foll of negative thickness is intorduced between two plates of a capacitor at the center. What will be the new capacitance of the capacitance ?

A sheet of aluminium foil of negligible thickness is placed between the plates of a capacitor of capacitance C as shown in the figure then capacitance of capacitor becomes

Two metal plates form a parallel plate capacitor. The distance between the plates is d. A metal sheet of thickness d/2 and of the same area is indroduced between the plates. What is the ratio of the capacitances in the two cases?

AN air filled parallel plate capacitor has a capacitance of 2.1 pF. The separation of the plates is doubled, and wax is inserted between them . The new capacitance is 2.6 p F Find the dielectric constant of the wax.

parallel plate capacitor has capacitance C when no dielectric between thw plates. Now a slab of dielectric constant K , having 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

For changing the capacitance of a given parallel plate capacitor, a dielectric material of dielectric constant K is used, which has the same area is the plates of the capacitor. The thick of the directrie slab is (3)/(4)d, where ‘d’ is the separation between the plates of parallel plate capacite. The new capacitance (C') in terms of original capacitance (C _(0)) is given by the following relation:
