WebbOhm's Law states that the current flowing in an electric circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the material. Ohm's Law … Webbbe asked if Ohm's law would still be valid. To answer that question one could refer to some laws and theories, but these led to two diverging results. Both arguments were based on the idea of the current-flow as a movement of electrons that could be treat ed as a flow of fluid and the equations of hydrodynamics could then be applied. The WebbOhm’s law is an empirical law like that for friction, which means that it is an experimentally observed phenomenon. The units of resistance are volts per ampere, or V/A.

WebbBy using the expression for drift velocity, electric current (in terms of drift velocity), and connection between electric field and potential, we can derive Ohm's law. Created by Mahesh Shenoy. sir, quick question how are we getting resistance R, by substuting the values of I with respect to drift velocity. so if I is all the values that makes ... Webb1 Ω = 1 V/A (1.4). Ohm’s law holds for most materials and at common temperatures. At very low temperatures, resistance may drop to zero (superconductivity). At very high temperatures, the thermal motion of atoms in the material inhibits the flow of electrons, increasing the resistance.
