WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Explain why a light bulb does not follow ohm's law. I understand that the … WebJun 26, 2024 · First off, Ohm's law is not the equation V = I R alone. Instead, V = I R is significant in at least two different ways, only one of which is properly called as "Ohm's law": One of these is that it is a definition of "resistance" as a physical quantity. In that case, it would perhaps better be written as R := V I .

WebNo, the faster you push the electron the more energy i takes to push it. the max speed we have sent an electron at is 99.9999992% of the speed of light and takes 4 billion eV to do so. the problem is that the faster you push the electron it acts as though it is getting heavier and therefore takes more energy to push. 3 comments ( 113 votes) Flag Web6. No, the light bulb doesn't follow ohms law. The Voltage is not proportional to current in this case. And for ohms law to be valid resistance should be constant but in the case of light bulb resistance changes. For a filament bulb as we switch on the bulb the temperature of filament increases and hence resistance increases.

WebThe 68Ω resistor did follow Ohm’s Law, as it stayed true to the linear slope of 66 which is close enough when considering imprecision of equipment used, to the theoretical value of 68. ... It is not a good idea to power light bulbs using constant current rather than constant voltage because this could cause low resistance of the filament or ...

After doing the Electric Potential vs Electrical Current Lightbulb … how to change job interests on linkedinWebAug 29, 2024 · Yes, a lightbulb does follow Ohm’s law. For a lightbulb to work, it needs a certain amount of current (measured in amps) to flow through it. The resistance of the lightbulb determines how much current will flow. If the lightbulb has a high resistance, then less current will flow; if the lightbulb has a low resistance, then more current will flow. michael keaton family photosWebAug 15, 2024 · Ohm’s law (like Hooke’s law) is not universally valid. The many substances for which Ohm’s law holds are called ohmic. These include good conductors like copper and aluminum, and some poor conductors under certain circumstances.
