#### Drift of Electrons and the Origin of Resistivity - Study …

Drift of Electrons and the Origin of Resistivity. We know that under normal circumstances the free electrons move randomly from one atom to another. The velocity with which this random motion is taking place is called Thermal Velocity. The average thermal velocity is said to be zero as the entire motion on an average is random.
