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.
  • D
    None of these.
✓

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.
