![]() The same thing is true for electric flux. Assume one is asked to pass out water through a ring, on which position does he/she expect the maximum flow of water? This happens as the area of the ring becomes perpendicular to the flow of water. Solution: Electric flux is defined as the amount of electric field passing through a surface of area A with the formula \(\Phi_e=\vec\)Įlectric Flux is a variable quantity as it relies on the direction of the electric field and the orientation of the planar object. Find the electric flux through the surface. The electric field stands for the symbol Φ (phi) and is defined by: Φ = E Δ SĮxample: A uniform electric field with a magnitude of E = 400 N/C incident on a plane with a surface of area A = 10m 2 and makes an angle of θ = 30 ∘ with it. The S.I unit of electric flux is given in Newton meters squared per coulomb. If we put in place an electric field with flowing water, we define it as electric flux.īecause the strength of the electric field is directly proportional to the number of lines passing per unit area, electric flux also indicates the strength of the electric field. ![]() If there is some angle θ between the velocity of liquid and surface area dS and flux of liquid, can be calculated from the given relation: This flow of liquid, which is given by the quantity v dS, is called flux. ![]()
