The plates of a parallel plate capacitor with air as medium are separated by a distance of `8 mm`. A medium of dielectric constant 2 and thickness `4 mm` having the same area is introduced between the plates. For the capacitanace to remain the same, the distance between the plates is

Separation between the plates of a parallel plate capacitor is d and the area of each plates is A . When a slab of material of dielectric constant k and thickness t(t lt d) is introduced between the plates. Its capacitance becomes

Separation between the plates of a parallel plate capacitor is d and the area of each plates is A . When a slab of material of dielectric constant k and thickness t(t lt d) is introduced between the plates. Its capacitance becomes

The two plates of a parallel plate capacitor are 4 mm apart. A slab of dielectric constant 3 and thickness 3 mm is introduced between the plates is so adujected that the capacitance of the capacitor becomes (2)/(3) rd of its original value. What is the new distance between the plates ?

The two plates of a parallel plate capacitor are 4 mm apart. A slab of dielectric constant 3 and thickness 3 mm is introduced between the plates is so adjusted that the capacitance of the capacitor becomes (2)/(3) rd of its original value. What is the new distance between the plates ?

The plates of a parallel plate capacitor are charged up to 200 V. A dielectric slab of thickness 4 mm is inserted between its plates. Then, to maintain the same potential difference between the plates of the capacitor, the distance between the plates increased by 3.2 mm. The dielectric constant of the dielectric slab is

Two plates of a parallel plate capacitor are 4 mm apart. A slab of dielectric constant 3 and thickness 3mm is introduced between the plates with the faces parallel to them. The distance between the faces is so adjusted that the capacitance of the capacitor becomes 2/3 of its original value. What is the new distance between the plates ?

The capacitance of a parallel plate condenser with a separation of 4 mm between the plates is 7muF . If a mica sheet (K=6) of thickness 2 mm and of the same area is introduced betwenn the plates, its capacitance will be

The separation between the plates of a parallel plate capacitor is d and the area of each plate is A. iff a dielectric slab of thickness x and dielectric constant K is introduced between the plates, then the capacitance will be
