Electric Flux Density Calculator

More Information

Electric Flux Density (D) is used in electromagnetism to describe how electric fields interact with materials — particularly dielectrics (insulators).

Tap / click on two of the three abbreviations above (as appropriate) and enter the value known, select the appropriate units, then click the 'Calculate' button for instant results.

What to use this calculator for:

1. Capacitor design

This tool calculates how much charge a dielectric material can store in a capacitor. Used to optimize dielectric strength and capacitance.

2. Electric field analysis in materials

Especially useful when fields pass through non-vacuum environments (plastics, glass, etc.). Electric Field analysis accounts for how materials polarize in an electric field.

3. Boundary conditions

In electromagnetic boundary problems, 'D' is continuous perpendicular to the boundary between two materials. It helps determine how the electric field changes across interfaces.

4. Gauss's Law in Dielectrics

Gauss' Law ( D = Q / A ) is used to find fields when free charges exist in dielectric regions.
