Explain what would happen if in the capacitor of 18muF a 3mm thick mica sheet (of dielectric constant = 6) were inserted between the plates : while the voltage supply of 100 V remained connected,

The plates of a parallel plate capacitor have an area of 90 cm^2 each and are separated by 5.5 mm. The capacitor is charged by connecting it to a 400 V supply. Arrive at a relation between u and the magnitude of electric field between the two plates.

A parallel plate capacitor of capacitance 90 pF is connected to a battery of emf 20V. If a dielectric material of dielectric constant k=(5)/(3) is inserted between the plates, the magnitude of the induced charge will be

The plates of a parallel plate capacitor have an area of 90 cm^2 each and are separated by 2.5 mm. The capacitor is charged by connecting it to a 400 V supply. View this energy as stored in the electrostatic field between the plates and obtain the energy per unit volume (u).

A parallel plate capacitor of plate area A and plate separation d is charged to a potential difference V and then the battery is disconnected. A slab of dielectric constant k is then inserted between the plates of the capacitor so as to fill the space between the plates. If Q, E and W denote respectively the charge on each plate, the electric field between the plates and the work done in the process of inserting the slab, then
