Question

What is the difference between resistance and resistivity of the conductor? What would happen to the resistance of a wire if it is stretched to double it's length? Justify your answer

Answer 1

Hello Friend☺
in simple term ,Resistance Is obstruct in the path And property Of resistance is called.................. Resistivity ....If Wire is streched to double then the resistance ........decreases because It is inversely proportional .
☺

Answer 2

resistivity is the in which resistance of perunit and perunit aera of cross section while resistance property inwhichby virtue of its oppose flow of charge

resistance becomes 4 times because length double and area halved dueto strech
