## What is Drift Velocity Calculator?

Drift Velocity Calculator are physic/math calculator to find drift velocity (average velocity of a particle), current, charge carrier number density or cross-sectional area of a wire fast and easy.

Features:
- Instant calculation
- Result are copy able to other app
- Formula are include as reference
- Support up to 16 decimal place
- Support various unit for each input

Drift Velocity Calculator calculate the velocity of any charged particle in a specific material. eg the current speed in a cable.

The drift velocity is the average velocity that a particle, such as an electron, attains in a material due to an electric field. It can also be referred to as axial drift velocity. In general, an electron will propagate randomly in a conductor at the Fermi velocity.

formula:

u = I / (n * A * q)

where:
u - drift velocity (average velocity of a particle)
I - current 
n - charge carrier number density
A - cross-sectional area of a wire
q - charge on the charge carrier
