The voltage-current plot of a wire of resistance R is illustrated below. If the wire has length l=1m and cross-sectional area A=2x10^-5m^2, what is the wire\'s resistivity, p? (hint: find and use the resistance R.)
Solution
Image not visible ,Here From the slope graph you can find the resistance of the wire.i.e
R=Slope of the graph
Since Resistance
R=pL/A
Resistivity of wire is
p=RA/L =R*(2*10-5)/1 =(2*10-5)R
IF you cannot find the slope of the graph ,please provide me the figure ,i will solve it
