Enter the current density (amps/mm^2) and the total area (mm^2) into the calculator to determine the Current From Current Density.

Current From Current Density Formula

The following formula is used to calculate the Current From Current Density.

I = ID * A

• Where I is the Current From Current Density (amps)
• ID is the current density (amps/mm^2)
• A is the total area (mm^2)

How to Calculate Current From Current Density?

The following two example problems outline how to calculate the Current From Current Density.

Example Problem #1:

1. First, determine the current density (amps/mm^2). In this example, the current density (amps/mm^2) is measured to be 50.
2. Next, determine the total area (mm^2). For this problem, the total area (mm^2) is calculated to be 12.
3. Finally, calculate the Current From Current Density using the formula above:

I = ID * A

Inserting the values from above and solving the equation with the imputed values gives:

I = 50 * 12 = 600 (amps)

Example Problem #2:

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

current density (amps/mm^2) = 14

total area (mm^2) = 11

Entering these values into the formula or calculator above gives us::

I = 14 * 11 = 154 (amps)
