The diameter of a copper wire is 2mm, if a steady current of 6.25 A is caused by `8.5xx10^(28) //m^(3)` electrons flowing throught it. Calculate the drift velocity of condu ction electrons.

A copper wire of diameter 1.0 mm carries a current of 0.2 A. Copper has 8.4xx10^(28) atoms per cubic metre. Find the drift velocity of electrons, assuming that one charge carrier of 1.6xx10^(-19) C is associated with each atom of the copper.

The magnitude of current density in a copper wire is 500 A//cm^2 . If the number of free electrons per cm^3 of copper is 8.47 xx 10^22 , calculate the drift velocity of the electrons through the copper wire (charge on an e = 1.6 xx 10^-19 C).

A copper wire of cross-sectional area 0.5 m m^(2) carries a current of 0.2A. If the free electron density of copper is 8.4xx10^(28)m^(-3) then compute the drift velocity of free electrons.

A copper wire of 2.5 xx 10^-6 m^2 area carries a current of 1.6A. If the number density of the electrons in the wire is 8 xx 10^28//m^3 , then calculate the drift speed of the electrons in the wire (e = 1.6 xx 10^-19 C)

Cross-sectional area of a Copper wire is equal to area of a square of length 2 mm. If this copper wire draws 8 A electric current, then find the drift velocity of free electron. Number density of electron in Copper wire is 8 xx 10^(28) m^(-3)
