Does a light bulb obey ohm's law
WebApr 5, 2024 · Ohm’s law may be expressed mathematically as V / I = R. That the resistance, or the ratio of voltage to current, for all or part of an electric circuit at a fixed temperature is generally constant had been established by 1827 as a result of the investigations of the German physicist Georg Simon Ohm. Web4, light bulb) do not obey Ohm’s Law. Ammeters are connected in series so that the cur-rent flows through them. The ideal ammeter has a re-sistance of zero so that it has no e↵ect on the circuit. Real ammeters have some internal resistance. Voltmeters are connected in parallel to resistive elements in the circuit so that they measure the ...
