ELECTROSTATIC POTENTIAL AND CAPACITANCE Set 5

Three capacitors of capacitance are connected in parallel to which a capacitor of capacitance is connected in series. Effective capacitance is 3.75, then capacity of each capacitor is

A solid conducting sphere having a charge us surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. if the shell is now given a charge the new potential difference between the same two surface is

A slab of copper of thickness is inserted in between the plates of parallel plate capacitor as shown in figure. The separation between the plates is if , then the ratio of capacities of capacitors after and before inserting the slab will be

Three capacitors each of capacitance 1F are connected in parallel. To the combination, a fourth capacitor of capacitance 1 F is connected in series. The resultant capacitance of the system is

In the arrangement of capacitors shown in figure, each capacitor is of 9F, Then the equivalent capacitance between in points A and B is
