Please Help Me, By The provided Data Prepare a graph and Using that Graph Calculate the Value of Resistivity.Mean Diameter Of used Wire in the Ohms Law Experiment is 0.051cm and Length of wire Is 111cm

Dear Student
Such questions are made for enhancing the self creative skills and should be tried answering on your own. However, here are a few points that will help you in framing your answer:
. First plot the graph with I on x axis and V on Y axis

.Ypu will get straight line as per Ohm's law . V=IR
.Slope of the line gives resistance, R = V/I
.$$\begin{gathered} Here i am calcualting R from first and last reading \\ R =\frac{△V}{△I} =\frac{1.8-1}{330-150} =\frac{0.8}{180}=0.0044 ohm \\ Diameter = 0.051 cm \\ r =\frac{0.051}{2} =0.0255 cm=0.0255\times {10}^{-2} m \\ l= 111 cm =111\times {10}^{-2} m \\ Resistivity \rho =\frac{RA}{l} =\frac{R{\mathrm{\pi r}}^2}{l} =\frac{0.0044\times 3.14\times 0.0255\times {10}^{-2} \times 0.0255\times {10}^{-2} }{111\times {10}^{-2} m} \\ \rho =8.1\times {10}^{-10} ohm.m \end{gathered}$$
