Displacement Current Formula
The following formula is used to calculate the Displacement Current.
Id = Jd * S
- Where Id is the Displacement Current (amps)
- Jd is the displacement current density (amps/mm^2)
- S is the area of the capacitor (mm^2)
How to Calculate Displacement Current?
The following two example problems outline how to calculate the Displacement Current.
Example Problem #1:
- First, determine the displacement current density (amps/mm^2). In this example, the displacement current density (amps/mm^2) is measured to be 20.
- Next, determine the area of the capacitor (mm^2). For this problem, the area of the capacitor (mm^2) is calculated to be 31.
- Finally, calculate the Displacement Current using the formula above:
Id = Jd * S
Inserting the values from above and solving the equation with the imputed values gives:
Id = 20*31 = 620 (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:
displacement current density (amps/mm^2) = 5
area of the capacitor (mm^2) = 105
Entering these values into the formula or calculator above gives us::
Id = 5 * 105 = 525 (amps)
