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
✓

Answer

  1. None of these.
Explanation:
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.
