If length of a conductor is doubled by keeping volume constant, then what is its new resistance if initial were `4Omega` ?

If the radius of cross-section of the conductor is increased by 0.1 % keeping volume constant, then percentage change in the resistance of the conductor is

If the radius of cross-section of the conductor is increased by 0.1 % keeping volume constant, then percentage change in the resistance of the conductor is

The length of a conductor is doubled and its radius is halved, its specific resistance is

If the length of a conductor is increased by 100% keeping its area of cross-section constant, the percentage increase in its resistance is

If the length of a conductor is increased by 100% keeping its area of cross-section constant, the percentage increase in its resistance is

A long solenoid has self inductance. L. If its length is doubled keeping total number of turns constant then its new self inductance will be

A long solenoid has self inductance. L. If its length is doubled keeping total number of turns constant then its new self inductance will be

If the length of a conducting wire be doubled by stretching, its resistance compared to the initial value will be :

The resistance of a wire R Omega . The wire is stretched to double its length keeping volume constant. Now, the resistance of the wire will become
