Two identical capacitors are connected as shown in the figure. A dielectric slab is introduced between the plates of one of the capacitors so as to fill the gap, the battery remaining connected. The charge on each capacitor will be :(charge on each condenser is $$q_{0}$$;  $$k$$  = dielectric constant )

A parallel plate capacitor of capacity $$5 \mu F$$ and plate separation $$6 cm$$ is connected to a $$1V$$ battery and is charged. A dielectric of dielectric constant $$4$$ and thickness $$4 cm$$ is introduced into the capacitor. The additional charge that flows into the capacitor from the battery is:

The capacity between the points A and B in the given circuit will be:

The capacitance $$C_{AB}$$ in the given network is:

The equivalent capacitance $$C_{AB}$$ of the circuit shown in the figure is :

The effective capacity between A and B of the given network is

An air filled parallel plate capacitor has a capacitance $$1 pF$$. The separation between the plates is doubled and wax is inserted between the plates, then the capacitance becomes $$2 pF$$. What is the dielectric constant of wax ?

An isolated parallel plate capacitor is charged upto a certain potential difference. When a $$3mm$$ thick slab is introduced between the plates then in order to maintain the same potential difference, the distance between the plates is increased by $$2.4mm$$. Find the dielectric constant of the slab. (Assume charge remains constant)

The capacity of a parallel plate condenser without any dielectric is C. If the distance between the plates is doubled and the space between the plates is filled with a substance of dielectric constant $$3$$, the capacity of the condenser becomes:

A parallel plate capacitor is connected to a cell. It's positive plate A and the negative plate B have charges $$+Q$$ and $$-Q$$ respectively. A third plate C identical to A and B with charge $$+Q$$ is  now introduced midway between the plates A and B parallel to them What is the charge on the inner surface of A ?
