When a current is established in a wire, the free electrons drift in the direction opposite to the current, Does the number of free electrons in the wire continuously decrease?

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. Average thermal velocity of the electron is

When the free electrons are moving in all ossible directions, the value of the current proeduced is _________

Statement I: The drift velocity of free electrons is v_d when a current l passes through a copper wire. The drift velocity is halved when the same current passes through another copper wire of double the diameter. Statement II: For the same current, the drift velocity of free electrons in a metal wire is inversely proportional to the area of cross section of the wire.

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity.

A small insect crawls in the direction of electron drift along bare copper wire that carries a current of 2.56A. It travels with the drift speed of the electron in the wire of uniform cross-section area 1mm^2 Number of free electrons for copper = 8 times 10^28// cc and resistivity of copper = 1.6 times 10^-8 Omega m How much time would the insect take to crawl 1.0 cm if it crawls at the drift speed of the electron in the wire?
