Hypothesize as to why the data is linear at low voltages/currents, and then deviates at higher values. (Hint: our eyes tell us that the light intensity is higher for these higher voltages/currents. Assuming the temperature of the bulb filament corresponds to the light intensity, what can we say about the how the resistance of the filament changes with temperature? A simple qualitative answer is all that is sought here.)
