How to Use

Using the drift velocity calculator is quite straightforward. Below are the steps to follow:

1. Input the Required Parameters: You will need to provide values for charge carrier density (n), charge of the carriers (q), and current (I).
2. Click Calculate: After inputting the parameters, simply click on the “Calculate” button.
3. Read Your Results: The calculated drift velocity will display instantly, allowing you to analyze and utilize the data.

Formula

The formula for calculating drift velocity (v_d) is derived from the relationship between current (I), charge carrier density (n), charge (q), and cross-sectional area (A). It is given by:

v_d = I / (n * q * A)

Where:

• v_d: Drift Velocity (m/s)
• I: Electric Current (Amperes)
• n: Charge Carrier Density (carriers/m³)
• q: Charge of Carriers (Coulombs)
• A: Cross-Sectional Area (m²)

Example Calculation

To illustrate its application, let’s calculate the drift velocity using a practical example:

Suppose we have the following parameters:

• Current (I): 5 Amperes
• Charge Carrier Density (n): 1 x 10^28 carriers/m³
• Charge of Carriers (q): 1.6 x 10^-19 Coulombs
• Cross-Sectional Area (A): 0.01 m²

Using the formula:

v_d = I / (n * q * A)

Substituting in the values:

v_d = 5 / (1 x 10^28 * 1.6 x 10^-19 * 0.01)

Calculating the drift velocity, we find:

v_d = 5 / (1.6 x 10^9) ≈ 3.125 x 10^-9 m/s
