Drift Velocity #!#Current density #!#Introduction

a. A steady current flows in a metallic conductor of non - uniform cross section. State which of the quantities i.e., current density, electric field, and drift velocity, current density, electric field, and drift velcoity remain constant? b. A steady current passes through a cylindrical conductor. Is there an electorn field inside the conductor?

Average and instantaneous current | Drift velocity | Mobility| Current density | Ohm's experimental law | Ohm's Law from drift velocity | Temperature dependence of resistivity for conductors | semi comductors and super conductors | Temperature dependence of resistance

If A is the area of cross section of conductor, v_(d) is the drift velocity of electrons and n is the number of electrons per unit volume, then current density through conductor is

The drift velocity of free electrons in a conductor is v, when a current i is flowing in it, Ifboth the radius and current are doubled, then the drift velocity will be :

The drift velocity of free elecrons in a conductor is v , when a current i is flowing in it. If both the radius and current are doubled, then the drift velocity wil be

State Ohm' law and deduce it from the knowledge of drift velocity of free electrons in a conductor carrying current.

The drift velocity does not depend upon

A current of 16 A is made to pass through a conductor in which the number of density of free electrons is 4xx10^(28)m^(-3) and its area of cross section is 10^(-5)m^(2) . The average drift cross section is 10^(-5)m^(2) . The average drift velocity of free electrons in the conductor is
