Question

What is the drift speed of electrons in a conductor? Find an
expression of it.​

Answer 1

Answer

A drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. According to drift velocity expression, the relaxation time is the time interval between successive collisions of an electron on increasing temperature, the electrons move faster and more collisions occur quickly. Hence, relaxation time decreases with increase in temperature which implies that drift velocity also decreases with temperature.
