WebOhm’s law relates the resistance of a component to its voltage and current. Applying circuit rules for current and voltage with Ohm’s Law allows us to formulate rules to determine … WebJun 28, 2024 · The reason Ohm's Law is so simple is that when electrons are flowing in a conductor, the underlying physical process is rather like water flowing in a pipe - electrons can move from atom to atom with some resistance that is (roughly) independent of the voltage. However, Ohm's Law has its limits. blue moschino t shirtWebDec 6, 2024 · Ohm’s Law determines what current is formed when you apply a force to charges. This results in J = σ E for Coulomb forces. But you are free to specify any force (electric, magnetic, etc.). Then the same procedure leading to J = σ E applies, just instead of only using F = N q E, you include the other terms.
