WebAug 20, 2024 · To determine if a lightbulb is an ohmic resistor we decided to measure the current and voltage at twelve different data points. These data points ranged from +6.0V to -6.0V with 1V increments. The data was then plotted on a scatter plot as voltage vs current to determine if there was a linear trend. Weba material behaves in this way, it is called “ohmic.” Electrical components made from ohmic materials are called resistors. By measuring the current ﬂowing through a component as a function of the voltage across the component, one can determine whether the ratio DV/I is a constant or not. If it is constant, then the 28

"Webmaterials and devices can also act like resistors; a light bulb filament, for example, usually consists of a thin tungsten wire with its two ends connected to separate parts of the metal base. (See fig. 1b.) Like most (but not all) solid materials, graphite and tungsten are ohmic, which means that resistors made from them obey Ohm’s Law, V=IR. " - Determining if light bulb is ohmic
