Capacitance Of Plates With Dielectric

Dielectric||Capacitance with Dielectric||Dielectric with Battery and Without Battery

A parallel plate capacitor with oil as a dielectric between the plates has a capacitance C. if the oil, with dielectric constannt (K=3), is removed, then the capacitance of the capacitor will be

There is an airfilled capacitor of capacity C. when the plate separation is doubled and a dielectric is introduced between the plates, the capacitance becomes 2 C. the dielectric constant of the dielectric 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 plates is introduced so as to fill one-fourth of the capacitor as shown in the figure. The new capacitance will be :

A slab of material of dielectric constant K has the same area as the plates of a parallel plate capacitor, but has a thickness 3d//4 . Find the ratio of the capacitanace with dielectric inside it to its capacitance without the dielectric.

A parallel plate capacitor is filled with dielectrics as shown in Fig. What is its capacitance ?

Derive an expression for the capacitance of a parallel-plate capacitor filled with a dielectric.

Explain why the capacitance of a parallel plate capacitor increases when a dielectric slab is introduced between the plates.

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
