The number density of conduction electrons in a copper conductor is 8.5xx10^(28) m^(-3) . How long does an electron take to drift from one end of a wire 3.0 m long to its other end ? The area of cross-section of the wire is 2.0xx10^(-6) m^(2) and it is carrying a current of 3.0 A.

The number density of free electrons in a copper conductor is estimated at 8.5 xx 10^(28) m^(-3) . How long does an electron take to drift from one end of a wire 3.0 m long to its other end? The area of cross-section of the wire is 2.0 xx 10^(-6)m^(2) and it is carrying a current of 3.0A.

Subtract 2.5xx10^(-5)" from "8.0xx10^(-3) with regards to significant figure.

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.
