A parallel-plate capacitor having plate are `100 cm ^2 `and separation 1.0 mm holds a charge of 0.12 muC when connected to a 120 V battery. Find the dielectric constant of the material filling the gap.

A parallel plate capacitor a air between its plates having plate area of 6*10^-3 m^2 and separation between them 3 mm is connected to a 100 V battery. Explain what would happen when a 3 mm thick mica sheet (of dielectric constant = 6) were inserted between the plates, while the voltage supply remained connected.

A parallel plate capacitor a air between its plates having plate area of 6*10^-3 m^2 and separation between them 3 mm is connected to a 100 V battery. Explain what would happen when a 3 mm thick mica sheet (of dielectric constant = 6) were inserted between the plates, after the supply was disconnected.

A parallel plate capacitor of plate area A and plate separation d is charged to 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 magnitude of charge on each plate, the electric field between the plates (after the slab is inserted), and work done on the system, in question, in the process of inserting the slab,
