A parallel plate capacitor is constructed using three different dielectric materials as show in the figure
The parallel plates across which a potential difference is applied are of area A `= 1cm^2` and are separated by a distance d = 2 mm. If `k_1 = 4, K_2 = 2,k_3=6`, find the capacitance across the points A and B.

In the circuit show it the figure Find the phase difference between potential differences across C and R2

A parallel plate capacitor is maintained at a certain potentail difference. When a 3mm thick slab is intorduced between the plate, in a order to maintain the same potential difference, the distance between the plates is increased by 2.4 mm. Find the dielectric constant of the slab.

A parallel plate capacitor has a capacitance of 2muF . A slab of dielectric constant 5 is inserted between the plates and the capaitor is charged to 100 V and then isolated. What is the new potential difference, if the dielectric slab is removed?
