# 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**
