# Electron Gain Calculation

Drift velocity refers to the average velocity of a carrier that is moving under the influence of an electric field in a semiconductor, conductor, or electron tube. In a current-carrying circuit, a charged particle is accelerated by an electric field. It also undergoes frequent collisions with the stationary ions of the wire material.

Formula

V = I /(n*Q*A)

This advanced online Drift Velocity Calculation tool is used to calculate and find the drift velocity of electrons.

Example:
Calculate the drift velocity for the given details.
Flow of current (I) = 20
Number of electrons (n) = 30
Cross section of area of wire (A) = 15
Charge of electron (Q) = 10

Solution:
Apply Formula:
V = I /(n*Q*A)
V = 20/(30*15*10)
V = 20/ 4500
V = 0.0055555555
Drift velocity V) = 0.0055555555
