Ohm's law holds for circuits containing only resistive elements (no capacitances or inductances) for all forms of driving voltage or current, regardless of whether the driving voltage or current is constant or time-varying such as AC. At any instant of time Ohm's law is valid for such circuits. See more Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual … See more Ohm's law is an empirical law, a generalization from many experiments that have shown that current is approximately proportional to electric field for most materials. It is less fundamental than Maxwell's equations and is not always obeyed. Any given … See more A hydraulic analogy is sometimes used to describe Ohm's law. Water pressure, measured by pascals (or PSI), is the analog of voltage because … See more Ohm's law has sometimes been stated as, "for a conductor in a given state, the electromotive force is proportional to the current produced." That is, that the resistance, the ratio … See more In January 1781, before Georg Ohm's work, Henry Cavendish experimented with Leyden jars and glass tubes of varying diameter and length filled with salt solution. He measured the current by noting how strong a shock he felt as he completed the … See more The dependence of the current density on the applied electric field is essentially quantum mechanical in nature; (see Classical and … See more In circuit analysis, three equivalent expressions of Ohm's law are used interchangeably: Each equation is … See more WebFeb 20, 2011 · Despite its name, the generalized Ohm’s “law” is not strictly a law because it can be derived from more basic physical principles. These more basic physical principles …
