Electrostatic P...

A parallel plate capacitor consists of two circular plates each of radius 2 cm, separatrd by a distance of 0.1 mm If Voltage across the plates is at the rate of 5$$\times 10^{13}$$ V/s, then the value of displacement current is

For high frequency a capacitor offer

In an adjoining figure are shown three capacitors $$\mathrm { C } _ { 1 } , \mathrm { C } _ { 2 }$$ and  $$\mathrm { C } _ { 3 }$$ joined to a battery. The correct condition will be:

The value of equivalent capacitance of the combination shown in figure, between the points $$P$$ and $$Q$$ is

If electric intensity $$\overrightarrow { E } $$ is along the X-axis, then the equipotential surfaces are parallel to

The capacities and connection of five capacitors are shown in the adjoining figure. The potential difference between the points A and B is $$60$$ volts. Then the equivalent capacity between A and B and the charge on $$5\,\mu F$$ capacitance will be  respectively

The equivalant capacitance of the combination shown in figure below is

P, Q and R are three points in a uniform electric field. The electric potential is

The ratio of charge densities on the surface of two conducting spheres is 3 : 2. lithe radii of t: the spheres are 4 cm and 8 cm the ratio of the electric potential on the surfaces of the sphere 2 is

In the circuit shown, two parallel plate capacitors of capacitance $$C$$ and $$2C$$ consisting of plate of identical dimension. They are connected with an ideal battery of terminal voltage $$V$$ as shown in figure $$I$$. Now the capacitor smaller in volume is completely inserted into the other capacitor larger in volume and kept in symmetric position and then connection polarities of the plates are reversed as shown in figure $$II$$.
