Question

Define surface charge density and volume charge density of an electric charge
Also state its unit.
​

Answer 1

Answer:

In electromagnetism, charge density is the amount of electric charge per unit length, surface area, or volume. ... Surface charge density (σ) is the quantity of charge per unit area, measured in coulombs per square meter (C⋅m−2), at any point on a surface charge distribution on a two dimensional surface.
