Drift Velocity Calculator

Drift Velocity Calculator

Drift Velocity Calculator is used to calculate the drift velocity of the charged particle within a conductor. This electron gain calculator takes the value of the current, number of electrons, cross-section area, and charge of an electron to find drift velocity with steps.

What is the drift velocity?

 The average speed that charged particles—like electrons—achieve in a material due to an electric field is known as drift velocity in physics. The speed of an electron's drift

Current and drift velocities are inversely related. It is also proportional to the strength of an external electric field in a resistive substance. So, drift velocity can be used to illustrate Ohm's law.

Formula of Drift Velocity

V = I /(n*Q*A)

where 

• I = flow of current 
• n = Number of electrons
• Q = Cross section of area of wire
• A = Charge of electron

How to calculate drift velocity?

Follow the below examples to evaluate the drift velocity.

Example 1:

Calculate the drift velocity if flow of current = 13, no. of electrons = 21, cross-section area of wire = 23, and charge of electron = 32

Solution

Given data:

I = 13

n = 21

A = 23

e = 32

Using the formula:

V = I /(n*Q*A)

Calculations:

V_d = 13 / 21*23*32

V_{d =} 13 / 15456

V_{d =} 0.0008410973

Example 2:

Calculate the drift velocity if flow of current = 41, no. of electrons = 32, cross-section area of wire = 14, and charge of electron = 25

Solution      

Given data:

I = 41

n = 32

A = 14

e = 25

Using the formula:

V = I /(n*Q*A)

Calculations:

V_d = 41 / 32*14*25

V_{d =} 41 / 11200

V_{d =} 0.00366
