Electric flux is a measure of the flow of an electric field through a given surface. It is a scalar quantity and is measured in units of coulombs per square meter (C/m²).
Concentric spheres are a set of spheres that share the same center point. In the context of electric flux, they refer to two or more spherical conducting shells placed inside one another.
The electric flux of concentric spheres can be calculated using the equation Φ = Q/ε0, where Φ is the electric flux, Q is the charge enclosed by the inner sphere, and ε0 is the permittivity of free space.
Concentric spheres serve as a useful model for understanding the behavior of electric flux in a system with multiple conducting surfaces. This is because the electric field lines are perpendicular to the surface of the spheres, making it easier to visualize and calculate the electric flux.
The electric flux between concentric spheres is inversely proportional to the distance between them. As the distance decreases, the electric flux increases, and vice versa. This relationship follows the inverse square law, where the electric flux is proportional to 1/r², where r is the distance between the spheres.
