SUMMARY
The average thermal velocity of free electrons in metals is zero in the absence of an electric field, as established in Classical Free Electron Theory. This principle indicates that, at thermal equilibrium, electrons do not exhibit a net current, preventing charge accumulation in any part of the metal. Such accumulation would violate thermodynamic laws and disrupt the equilibrium state. Therefore, the thermal velocity distribution of electrons remains balanced, ensuring no directional movement on average.
