Electrostatic P...

A metal plate of thickness half the separation between the capacitor plates of capacitance C is inserted. The new capacitance is:

The equivalent capacitance between P and Q of the given figure is (the capacitance of each capacitor is$$1\ \mu F$$ ):

A parallel plate capacitor is first charged and then isolated , and a dielectric slab is introduced between the plates. The quantity that remains unchanged is:

$$100J$$ of work is done when $$2 \mu C$$ charge is moved in an electric field between two points. The p.d. between the points is

When air is replaced by a dielectric medium of constant $$K$$, the capacity of the condenser:

$$1$$ volt is equal to

The work done in moving a single positive charge from infinity to a point is called ..... at that point

Three capacitors of $$3 \mu F, 2 \mu F $$ and $$6 \mu F$$ are connected in series. When a battery of 10V is connected to this combination then charge on $$3 \mu F$$capacitor will be :

Three equal condensers of capacity $$C$$ each are connected to form a triangle as shown above. The effective capacity across any side is  :

Which material sheet should be placed between the plates of a parallel plate condenser in order to increase its capacitance ?
