WebNo, a lightbulb is not an ohmic resistor. In an ohmic resistor, the resistance of the object always stays the same, meaning in the equation Resistance = Voltage / Current, when the voltage rises, the current rises proportionally … 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.
