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
Step-by-step solution
According to Ohm's law, for a conductor at constant temperature, the potential difference (V) is directly proportional to the current (I): V = IR. The graph of V versus I is a straight line passing through the origin. Therefore, it has no intercept on either axis (other than zero), so none of the options A, B, or C are correct.
