Enter the total charge and total surface area into the calculator to determine the surface charge density.
Surface Charge Density Formula
The following formula is used to calculate a surface charge density.
CD = q / A
- Where CD is the surface charge density (C/m^2)
- q is the total charge over the surface (C)
- A is the total area (m^2)
Surface Charge Density Definition
A surface charge density is a measure of electric charge per unit of area.
Surface Charge Density Example
How to calculate surface charge density?
- First, measure the area.
Measure the total area that has a charge.
- Next, measure the charge.
Measure the total electrical charge acting over the area from step 1.
- Finally, calculate the surface charge density.
Calculate the surface charge density by dividing the charge by total area.
FAQ
What is a surface charge density?
A surface charge density is a measure of charge acting on an object per unit area. Since charges often act on entire surfaces, it’s helpful to understand charges per unit area.
