Question

2 (a) Figure 4 shows the results from an experiment where the potential difference (voltage) across a filament lamp was varied. The current and voltage were measured.
(i) Describe the relationship between the current and the voltage as shown in the graph in Figure 4.

SnapAndSolve AI · Accepted Answer

(i) The graph in Figure 4 shows a nonlinear relationship between the current and the voltage across a filament lamp. As the voltage increases, the current also increases, but at a decreasing rate. This indicates that the resistance of the filament lamp increases with voltage, which is typical behavior for a filament lamp as it heats up.
