Question:
The ratio of resistance of conductor A and B given in graph is
A) 1 : 3
B) 3 : 1
C) 1 : root 3
D) root 3 : 1





​

Answer 1

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

$\sf{\dfrac{1}{ \sqrt{3} } \div \sqrt{3}}$

$\dfrac{1}{3}$

Option C)

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°

Resistance of A to B

Option C)

Slope = tan 60°

Resistance = √3
