Charge Density and conductor

Charge density

Linear charge density
λ=Q/L=dQ/dL

Surface charge density
σ=Q/A=dQ/dA

Volume charge density
ρ=Q/V=dQ/dV

Electrostatics in Conducter
1.E=0 inside the conducter
2. All charge resides on the outer surface of the conducter
3.Electric at the surface is Perpendicular to the surface
