Electric flux density, represented by the symbol D, is a measure of how electric field lines are distributed in a given area. It quantifies the amount of electric field passing through a surface per unit area.
Imagine you have a group of people standing in a crowded room. The electric flux density would be like measuring how many people are packed into each square meter of space.
Electric field strength (E): Electric field strength measures the force experienced by a charged particle at any point in an electric field.
Gauss's Law: Gauss's Law relates the total electric flux through a closed surface to the charge enclosed within that surface.
Permittivity of free space (ε₀): Permittivity of free space is a constant that relates the electric flux density to the electric field intensity and is used to calculate capacitance.
