Answer» Heya mate, Here is UR answer
Higher the slope of a line, less is the resistance. And we know that the CONDUCTOR that has the lowest resistance is the best conductor.
Now looking at the graph, we can say, that S has the HIGHEST slope meaning lowest resistance. So, S is the best conductor among all 4 .
2) We know that,
Resistance= RHO l/A
Now, rho( resistivity of the material) and l (length) is same, which is the thicker most.
More the resistance, less the area of cross section (thickness) .
To calculate the thickest WIRE, the resistance should be less.
Since the lowest resistance is of S, S must also have the largest area of cross section. Thus, S is the thickest wire.
