Question

note on electric flux

Answer 1

The orientation of area element decides the amount of electric flux. Thus, the area element is a vector.

The vector associated with every area element of a closed surface is taken to be in the direction of the outward normal.

Area element vector ΔS = ΔSn̂, ΔS is magnitude of area element and n̂ is unit vectorin the direction of outward normal.

Electric flux, Δφ = EΔS = E ΔScosθ, θ is angle between E and ΔS.

Unit of electric flux is NC-1m2.

Total flux through a surface, φ ≈ Σ EΔS
