Answer 1

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.

$<b><tt > here we go...$

⊙ Higher the slope of the line less is the resistance and lower the slope of the line high is the resistance.

⊙ so, S has the less resistance and the best conductor.

$now$

⊙ The thickest wire has the less resistance.

Hence , S is the thickest wire.
