Question

Define the term drift velocity of charge carriers in a conductor and write its relationship with the current flowing through it.

Answer 1

it is defined as the average velocity with which the electon in a conductor get drifted towards the positive end of the conductor under the applied potential is called drift velocity.

the relation between drift velocity and current is as follows

• i=nEAVd
• Where i=current
• n=charge density
• E=electric field
• A=area of cross section
• Vd=drift velocity

hope this will help you please mark as brain list answer.
