MCQ

A graph is plotted between the potential difference $($applied across the ends of a conductor$)$ and the current $($following through the conductor$)$. The graph is a straight line

A
Having intercepts on both axes.
B
Having an intercept on the $X-$axis.
C
Having an intercept on the $Y-$axis.
✓
None of these.

✓

Answer

Correct option: D.

None of these.

According to $Ohm's$ law, the potential difference across a conductor is directly proportional to the current through it.
$V = IR$
Hence the curve is a straight line passing through origin.
