A wire is drawn into double its length and half its original cross-section. What will be increase in its (i) resistance and (ii) resistivity?

A wire is drawn into double its length and half its original cross-section. What will be change in its resistance and specific resistance? Or. A wire of resistivity rho is stretched to twice its length. What will be its new resistivity ?

A wire of 10 Omega resistance is stretched to thrice its original length. What will be its (i) new resistivity and (ii) new resistance?

A wire of 10 ohm resistance is stretched to thrice its original length. What will be its (i) new resistivity and (ii) 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). " " 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.
