Question

Graph between electric current and potential difference across two conductors A and B made of same material are plotted as shown in the figure how do you relate the resistivity is of materials and b

Answer 1

Answer:

For comman voltage V Current in conductor B is greter then currecnt in conductor A.

ie i

B

>i

A

for same value of V

From ohms law,

R=

I

V

R∝

I

1

Hence,

If i

B

>i

A

R

A

>R

B

Option B
