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
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
Two point charge +3μCand+8μCrepel each other with a force of 40 N. If a charge of -5μC is added to each of them, then the force between then will become
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
