An experiment is carried out to investigate the electrical characteristics of a small filament lamp. Figure 1 shows the current-voltage characteristic obtained for the lamp.
Use the values of the potential difference and current at Point X and at Point Y on the graph in Figure 1 to complete the table in Figure 2. Figure 2
