Question

Graphs between electric current and potential difference across two conductors A and B are shown in the figure. Which of the following conductor has more resistance?

• A. B
• B. A
• C. Both have equal resistance
• D. None of these

Answer 1

The correct option is B A

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,

$R=\frac{V}{I}R\propto \frac{1}{I}$

Hence,

If $i_B>i_A$ $R_A>R_B$

Option B
