Determining if light bulb is ohmic
WebDec 30, 2024 · That's because the "resistance" of a light bulb does not directly depend on the voltage: It depends on the temperature of the filament, and the temperature depends on both the voltage and time. … 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.
