**Drift Velocity Calculator:** Have you been seeking a simple tool to calculate the average electron drift velocity? Then you've come to the right place. After taking the inputs, this user-friendly Average Drift Velocity Calculator gives the result as fast as possible. The drift velocity equation, as well as a thorough explanation of how to solve the drift velocity issues, may be found here. Learn what drift velocity is and how to solve questions about it in the sections below.

Electrons move in random directions all the time. When electrons are exposed to an electric field, they travel randomly at first but eventually drift in one direction, the direction of the applied electric field. Drift velocity is the net velocity at which these electrons drift.

The average velocity obtained by charged particles (e.g. electrons) in a material due to an electric field is known as drift velocity. Drift velocity is measured in millimetres per second (m/s). It's also measured in m^2/(V.s).

The movement of electric charge in a wire is known as an electric current. The velocity of free electrons moving from the positive end of the conductor due to the applied electric field is known as drift velocity. Drift velocity is measured in millimetres per second (m/s).

The drift velocity equation is as follows **v = I/(nAQ)**

The formula for calculating current is **I = nvAQ**

The formula to the calculating area is **A = I/(nvQ)**

- Where, v = drift velocity of the electrons
- I = current flowing through the conductor
- n = number of free electrons
- A = cross-section area of the conductor
- Q = charge of an electron

In the calculator, the number density represents the number of electrons per unit volume of the conductor.

The simplest step-by-step procedure for determining the drift velocity of charged particles is described below. Check the result by following these procedures.

- Step 1: Calculate the current, electron density, and area.
- Step 2: Multiply the area by the density of the numbers.
- Step 3: To calculate the drift velocity, multiply the current flow by the product.

**Question 1:**Calculate the drift velocity for the given details.
Flow of current (I) = 25
Number of electrons (n) = 33
Cross section of area of wire (A) = 20
Charge of electron (Q) = 10

**Solution:**

Given: (I) = 25, (n) = 33, (A) = 20, (Q) = 10

Apply Formula:

V = I /(n x Q x A)

V = 25/(33 x 10 x 20)

V = 25/ 6600

V = 3.78 x 10^-3 m/s

Drift velocity (V) = 3.78 x 10^-3 m/s

**Question 2:** A copper wire with a cross-sectional area of 2.0 mm^2 may carry a current of 1 A. Find the electron drift velocity if the number density of electrons in the wire is 13 x 10^28 carriers/m^3.

**Solution:**

Given:

Current flowing through wire I = 1 A

Cross-sectional area A = 2 mm^2 = 2 x 10^-6 m^2

Number density = 13 x 10^28 carriers/m^3

v = I/(nAQ)

= 1/(2 x 10^-6 x 13 x 10^28)

= 3.846 x 10^-24 m/s.

Therefore, the drift velocity of charged particles is 3.846 x 10^-24 m/s.

**1. What is the drift velocity order?**

The electron drift velocity in a conductor is on the order of 10^-4 m/s. When compared to the thermal speed, which is on the order of 105 m/s, it is insignificant.

**2. What is the drift velocity speed?**

In a metal wire, the individual electron velocity is frequently millions of kilometres per hour. The signal velocity is often a hundred million to a trillion kilometres per hour, but the drift velocity is typically only a few metres per hour.

**3. Is there a relationship between drift velocity and length?**

When dealing with a macroscopic (everyday life) wire, the drift velocity is independent of the wire's length or cross-sectional area.

**4. Does the diameter of the wire affect drift velocity?**

Drift velocity is unaffected by the conductor's diameter or cross-sectional area.

**5. What can be done to increase drift velocity?**

To begin, we can state that increasing the conductor's temperature increases the electrons' kinetic energy. As a result, their drift velocity should increase as the temperature increases.
