## 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)
