◾The graph between Potential Difference ( V ) and Current ( I ) is a straight line that passes though the Origin ( O )
◾The slope of the graph depicts that Current and Resistance are Inversely proportional to each other .
◾Due to the decreasing temperature , Resistance in a metallic wire increases due to more collisions between molecules .
