If the connections across a resistor are reversed, the graph between current and potential difference remains a straight line, but it will be in the opposite direction compared to the original graph. This is because a resistor follows Ohm's law, where current is directly proportional to voltage regardless of polarity, so the slope remains constant but on the opposite side of the origin.
If the connections across the resistor are reversed, then graph between current and potential difference is?
