Question

relation between drift velocity and relaxation time​

Answer 1

Answer:

drift velocity is proportional to the relaxation time . As the relaxation time increases the drift velocity increases,

Answer 2

The relation between drift velocity and relaxation time​ is as follows:

• The average velocity attained by the particles (due to an electric field), that is charged particles such as electrons is called the drift velocity.
• Vd = I/neA
• where Vd is the drift velocity
• I is the current
• n is the number of electrons
• e is the charge of the electron
• A is the cross section area of the wire
• The time interval between the two successive collisions of the electrons in a conductor is called the relaxation time.
• According to Ohm's law, the relaxation time is,
• J = σ E
