![]() Electric field is denoted by the symbol Φ (phi) and is represented as The S.I unit of electric flux is Newton meters squared per coulomb (N m 2 C −1). Since the strength of electric field is directly proportional to a number of lines passing per unit area, electric flux also signifies for determining the strength of electric field. Note: Flowing water and electric field are different terms, it is not necessary that something should flow in order to generate a flux. If we replace, an electric field with flowing water, we define it as electric flux. If there is some angle θ between the velocity of liquid and surface area dS and flux of liquid, can be evaluated from the relation: This flow of liquid, that is the quantity v dS, is called flux. Where dS is a surface area perpendicular to the velocity v of water, and v is the velocity of liquid (rate of change of length per unit time) The rate of flow of water will be volume passing through the area per unit time that is v dS.ĭifferentiating the above relation with respect to time, we get Suppose there a liquid flowing with velocity ‘v’, through tiny surface dS, in a normal direction with respect to the surface. Let’s understand what the term flux actually means, with an example. It is also defined as the product of electric field and surface area projected in a direction perpendicular to the electric field. It is another physical quantity to measure the strength of electric field and frame the basics of electrostatics. Image 1: Electric flux passing through a plane surfaceĮlectric Flux is defined as a number of electric field lines, passing per unit area. What if we want to present electric field in a three-dimensional form? This can be done with the help of electric flux.
