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. WebDec 21, 2024 · The Ohm's law formula can be used to calculate the resistance as the quotient of the voltage and current. It can be written as: R = V/I. Where: R - resistance. V …
