Question

the ratio of resistance of conductor A to B given in graph is:

Answer 1

sorry I can't help bcoz I can't understand the pic of graph

sorry my dear!!!!

Answer 2

ANSWER
________________________

"Slope of V-I graph gives Resistance"

Here the graph is of I-V
So, Consider the graph rotated 90° left

For A,
Angle will be 30°
Slope = tan 30°
Resistance = 1/√3

For B,
Angle will be 60°
Slope = tan 60°
Resistance = √3

Ratio of Resistance of A to B
$\frac{1}{ \sqrt{3} } \div \sqrt{3}$
$= \frac{1}{3}$

ANSWER IS (A) 1/3
