Electrical Properties of a Filament Lamp - Does a Filament Lamp Obey Ohm's Law? Prediction I predict that the filament lamp will not obey Ohm's law, as the temperature cannot be kept constant through a bulb. The brighter the bulb is the more heat will be released. Ohm's law only applies when the temperature is constant. I expect the amps to increase as the voltage does as well as the resistance, so I expect the graph to have a positive gradient. The graph will have voltage (V) plotted on the x-axis and the current (I) will be plotted on the y-axis. After the bulb has been lit there will be a steep gradient on the graph, but after a while the gradient will become less steep and slowly the graph will start to become more cureved, as the resistance will not be increasing at a constant rate. Scientific Explanation I came to my...
