A wire of resistance 18 ohm is drawn until its radius reduces 1//2^(th) of its original radius then resistance of the wire is

A piece of wire of resistance 20Ohm is drawn out so that its length is increased to twice its original length.Calculate the resistance of the wire in its new situation.

A uniform wire of resistance R is uniformly compressed along its length until its radius becomes n times the original radius. Now the resistance of the wire becomes

A uniform wire of resistance R is uniformly compressed along its length, until its radius becomes n times the original radius. Now resistance of the wire becomes

A wire of length l is drawn such that its diameter is reduced to half of its original diameter. If the initial resistance of the wire were 10 Omega , its resistance would be
