When we charge a conductor, we are raising or lowering its potential.

How is the direction of flow of current between two charged conductors determined by their potentials ?

When we hear a sound, we can identify its source from

A number of spherical conductors of different radii are charged to same potential. The surface charge density of each conductor is related with its radius as

Some charge is being given to a conductor. Then its potential : -

Assertion: All the charge in a conductor gets distributed on whole of its outer surface. Reason: In a dynamic system, charges try to keep their potential energy minimum.

If a charged spherical conductor of radius 5 cm has potential V at a point distant 5 cm its centre, then the potential at a point distant 30 cm from the centre will be

If a charged spherical conductor of radius 10 cm has potential V at a point distant 5 cm from its centre, then the potential at a point distant 15 cm from the centre will be

Capacitance of a conductor is 1muF . What charge is required to raise its potential to 100 V ?

When we change feeble sound to loud we increase its :

A charged spherical conductor of radius a and charge q is, surrounded by another charged concentric sphere of radius b(bgta) . The potential differece between conductors is V . When, the spherical conductor of radius b is discharged completely, then the potential difference between conductor will be
