Potential difference of 100 V is applied...

Potential difference of 100 V is applied to the ends of a copper wire one metre long. Calculate the average drift velocity of the electrons ? Compare it with thermal velocity at `27^@C`. Consider there is one conduction electron per atom. The density of copper is `9.0xx10^(3)kg//m^(3)`, Atomic mass of copper is 63.5 g. Avogadro's number `= 6.0 xx 10^(23)` per gram-mole. Conductivity of copper is `5.81 xx 10^(7)Omega^(-1)m^(-1)`. Boltzmann constant `= 1.38 xx10^(23)JK^(-1)`.
