What is Drift Velocity?
Drift velocity is the average velocity that a charged particle, such as an electron, attains due to an electric field. When an electric field is applied to a conductor, the electrons inside the conductor experience a force that causes them to move in a particular direction. The drift velocity is influenced by factors such as the magnitude of the electric field, the charge of the particle, and the mobility of the particle in the material.
How to Calculate Drift Velocity
The drift velocity of a charged particle can be calculated using the formula:
v_d = μ * E
Where:
- v_d is the drift velocity
- μ is the mobility of the charged particle in the material
- E is the magnitude of the electric field

Factors Affecting Drift Velocity
Several factors can affect the drift velocity of charged particles in a conductor:
- Electric field strength: A stronger electric field will result in a higher drift velocity.
- Charge of the particle: Particles with a higher charge will have a higher drift velocity under the same electric field.
- Mobility of the particle: The mobility of a charged particle in a material is a measure of how easily it can move through the material when subjected to an electric field. Higher mobility will result in a higher drift velocity.
Applications of Drift Velocity
Understanding drift velocity is essential in various fields, including:
- Electronics: Drift velocity is crucial in the design and operation of electronic devices such as transistors and diodes.
- Physics: Drift velocity plays a significant role in the study of electric currents and conductors.
- Engineering: Engineers use drift velocity calculations when designing electrical circuits and systems.
