Question

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
• D. none of these

Answer 1

The correct option is 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.
So none of the options is correct.
