Question

please answer me fast it is necessary ​

Answer 1

Explanation:

The graph b is of highst conducity

Answer 2

Answer:

option B

Explanation:

V = IR

I = V/R

slope of the graph m = 1/R (on comparing with y =mx)

R = resistivity L/A

we get current is inverse to resistance and resistance is directly proportional to resistivity

condutivity is the reciprocal of resistivity

so we get that the slope is proportional to conductivity

hence we get conductivity B >A
