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

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

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 diameler. If the initial resistance of the wire were 10Omega . its resistance would become

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

A wire of resistance 10 Omega is drawn out so that its length is thrice its original length. Calculate its new resistance (resistivity and density of the material remain uncharged). " " Or A wire of resistance 10 Omega is drawn out so that its length is increased by twice its original length. Calculate its new resistance.

A wire of resistance 10 Omega is drawn out so that its length is thrice its original length. Calculate its new resistance (resistivity and density of the material remain uncharged).
