WebMar 2, 2010 · Does your light bulb follow Ohm’s law? Base your answer on your experimental data. The light bulb seemed to follow Ohm’s law for the first few points, but the data began to curve into a steeper linear plot as voltage was increased. This is evident by the change in slop from 3.261 V/A for the first 3 points and 37.66 V/A for the last 10 … WebOne way to make such a bulb is to have a single filament, but place the voltage across different parts of it, depending on which brightness is desired. Again, Ohm's law plays a role in determining the fraction of the filament that the the voltage is placed across, and the resistance of the entire filament. WebFigure 2: Data from both the linear (ohmic) and power regions of voltage across the light-bulb verses current through the light bulb in red, and residuals in blue. The slope of the left graph, m 2, is equal to R 0, the resistance of the bulb at room temperature. On the right, m 2 represents the resistance’s dependence on current. birch communications webmail
