WebDrift velocity is directly proportional to current and also to the magnitude of an external magnetic field in the case of resistive material. Drift Velocity can be expressed in terms of Ohm’s law as μE where µ represents the electron mobility and E is the electric field. Table of Content Drift Velocity Net Velocity Calculation of Drift Velocity WebApr 5, 2024 · Hence, we can conclude that. ⇒ V I = R. ∴ V = I R which is Ohms law, where R = m l n e 2 A t . Note. For clarity we can derive the current and voltage relation with drift velocity from first principles. We know that. ⇒ I = d q d t where q is charged, and t is time. For a conductor the amount of charge moving is given by the total amount ...
