Explain surface charge density. Write it’s unit.

Answer»

Surface charge density: When the charge is distributed on a plane or curved surface, then charge per unit area is called surface charge density of charge and represented by σ.
∴ σ = \(\frac{q}{A}\)
Where q is charge on surface of area A
∴ Unit of σ = Cm-2
Example: If q charge is distributed uniformly on sphere of radius R, then surface charge density of the sphere \(\sigma=\frac{q}{4 \pi R^{2}}\).
