Drift Velocity Calculator
Introduction
Calculating the drift velocity of charged particles is a crucial aspect in physics and engineering, particularly in the study of current flow. The drift velocity calculator provided here offers a convenient way to determine this parameter, ensuring accuracy in your calculations.
How to Use
To utilize the drift velocity calculator, simply follow these steps:
- Input the electric current (I) in amperes.
- Enter the cross-sectional area (A) of the conductor in square meters.
- Provide the charge of the electron (e) in coulombs.
- Specify the number density of charge carriers (n) in electrons per cubic meter.
- Insert the length (L) of the conductor in meters.
Once you’ve filled in these values, click the “Calculate” button, and the calculator will provide you with the drift velocity.
Formula
The formula used in the drift velocity calculator is as follows:
Where:
- vd is the drift velocity,
- I is the electric current,
- n is the number density of charge carriers,
- A is the cross-sectional area of the conductor,
- e is the charge of the electron.
Example Solve
Let’s consider an example:
- I=2A
- n=8×1028m−3
- A=5×10−6m2
- e=1.6×10−19C
- L=0.1m
By inputting these values into the calculator, you find that the drift velocity (vd) is approximately
