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:
- First, determine the current density (amps/mm^2). In this example, the current density (amps/mm^2) is measured to be 50.
- Next, determine the total area (mm^2). For this problem, the total area (mm^2) is calculated to be 12.
- 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)
