" (e6.When the diameter of a wire is doubled,its resistance Decor "

When the diameter of a wire is doubled, its resistance becomes:

If the diameter of a resistance wire is halved, then its resistance becomes:

When a weight of 10 kg is suspended from a copper wire of length 3 metres and diameters 0.4 mm , its length increases by 2.4 cm . If the diameter of the wire is doubled, then the extension in its length will be

Resistivity of a material of wire is 3 * 10^(-6) Omega-m and resistance of a particular thickness and length of wire is 2 Omega . If the diameter of the wire gets doubled then the resistivity will be

If the length of a given conducting wire is kept constant and its diameter is doubled, what will be the resistance of the new wire?

A and B are identical wires. The length of wire A and diameter of wire B are doubled. The ratio of new resistances of A and B is
