Calculate Current Density (j)



Formula

The formula to calculate the Current Density (j) is:

\[ j = p \times v \]

Where:

Example

Let's say the charge density (\( p \)) is 5 C/m³ and the velocity of the charges (\( v \)) is 2 m/s. Using the formula:

\[ j = 5 \times 2 \]

We get:

\[ j = 10 \text{ A/m²} \]

So, the Current Density (\( j \)) is 10 A/m².

What is Current Density?

Current density is defined as the total current per unit of volume or area. It is a measure of the electric current (flow of electric charge) per unit area of cross-section.

Current Density

Definition: Current density is the amount of electric current flowing through a unit area of a cross-section.

Formula: \( J = \frac{I}{A} \)

Example: \( J = \frac{10}{2} \)

Electric Current Density

Definition: Electric current density is the measure of the flow of electric charge in amperes per unit area of cross-section.

Formula: \( J = \sigma \times E \)

Example: \( J = 5 \times 3 \)

Dimensional Formula of Current Density

Definition: The dimensional formula of current density represents its dimensions in terms of fundamental quantities.

Formula: \( [J] = [I][L]^{-2} \)

Example: \( [J] = [A][m]^{-2} \)
