If a charged spherical conductor of radius 10 cm has potential V at a point distance 5 cm from its centre, then the potential at a point distance 15 cm from the centre will be
The conventional current in a circuit is defined as " current which passes from a point at higher potential to a point at lower potential as if it represent a movement of
A uniform resistance wire of Length L and diameter d has a resistance R. Another wire of same material has length, 4L and diameter 2d, the resistance will be
The potential difference across the conductors should be maintained constant by connecting the ends of wire to the terminal of a device called a source of
Force acting upon a charged particle kept between the plates of a charged condenser if F. IF one of the plates of the condenser is removed, force acting on the same will become
