Calculate the average drift velocity of conduction electrons in a copper wire of sectional area 1.0×10^-7m^2,carrying a current of 1.5A.Assume that each copper atom contributes roughly one conduction electron.The density of copper is 9×10^4kgm^-3,the atomic weight 63.5and Avogadro's no.is 6.023×10^23 per mole.
