Question 15
Easy

A student plotted a graph of current against potential difference for a filament lamp.

Figure 1: A graph showing current in amperes (A) on the y-axis against potential difference in volts (V) on the x-axis. The y-axis ranges from 0 to 3.0 A. The x-axis ranges from 0 to 12.0 V. A smooth curve starts at the origin (0,0), passes through the point (2.0 V, 1.0 A), and curves as it rises to pass through the point (8.0 V, 2.0 A).

Use data from the graph in Figure 1 to show how the resistance of the filament lamp changes as the potential difference increases from 2.0 V to 8.0 V.
