WebA ductile metal wire has resistance R. What will be the resistance of this wire in terms of R if it is stretched to three times its original length, assuming that the density and resistivity of the material do not change when the wire is stretched? (Hint: The amount of metal does not change, so stretching out the wire will affect its cross-sectional area.) WebFeb 18, 2024 · If the original length of the wire is l and its cross-sectional area is A, then its resistance, R=ρl/A. When the length becomes 2l, cross-sectional area reduces to A/2 because volume of the wire does not change. Changes resistance, R′=ρ (2l) (A/2)=4ρlA=4R. iot in cement industry https://johntmurraylaw.com
