What is the drift velocity for the electrons in a calculator when an electric field of strength 200 V//m is applied on it and mobility of electrons is 4.5xx10^(-6) m^(2) V^(-1) s^(-1) ?

A copper wire of length 2.0 m, of cross-sectional area 2.0 mm square carries a current of 0.4A. It is assumed that there is only one electron per atom. Atomic mass of copper is 63 g and density of copper is 8.9g//c . Find the drift velocity for the electrons in the wire. Also find the mobility of electrons if a pot. difference of 100 V is applied across this wire.

The mobility of electrons is defined as the drift velocity acquird by electrons when a unit electric field is applied. Let a potential diffrence of 120 V be applied across a straight conductor of length 1m. What will be the drift speed of electrons if the mobility of electrons is given to be 6xx10^(-6)m^2V^(-1)s^(-1) ?
