What is thermal and drift velocity

1.	What is thermal and drift velocity
Answer» Drift velocity is the velocity in charge carriers owing to the potential difference applied at the ends of the material it is similar to the drift of the electrons in a conductor dur to the potential difference applied across.Whereas the thermal velocity is the velocity due to excitation of electrons by heat energy. The is kind of velocity causes the current due to heating called thermal current causing the thermal potential.
