## Introduction

In electromagnetism, displacement current is a crucial concept, especially in the context of capacitors and changing electric fields. It’s an essential part of Maxwell’s equations, which describe the behavior of electric and magnetic fields. The Displacement Current Calculator is a handy tool that simplifies the process of calculating displacement current, making it an invaluable resource for students, engineers, and researchers in the field of electromagnetism.

## The Formula

The Displacement Current ($Id$) is calculated using the formula:

**$Id=Jd∗S$**

Where:

- $Jd$ represents the displacement current density in amperes per square millimeter (A/mm²).
- $S$ is the area of the capacitor in square millimeters (mm²).

This formula forms the foundation for determining the displacement current in a given scenario.
