I am carring out an experiment using a 12 volt 5wtt bulb. When I apply 6,9 and 12 volts to the bulb it draws a current of 0.56, 0.697 and 0.825 amps respectively. To me it seems as though the filament resistance in the lamp is nonlinear.
Could you explain why this is so. That is if my assupmtions are correct.
Thanks
