Luminous flux refers to the line of visually transmitted radiated sensible energy per second.Įnergy or Radiant Flux refers to the radiated transmitted energy per second coming from any energy source. Magnetic flux refers to the number of times the magnetic field lines pass through a closed plane.Įlectric Flux refers to the number of times the electric field lines pass through a closed plane. There are different types of flux such as Mass Flux, Momentum Flux, Electric Flux, Magnetic Flux, Heat Flux, Luminous Flux, Radiant Flux, and Acoustic Flux. Therefore, the dimension of Electric Flux is. So, the dimension of electric flux is = dimension of electric field x area. Θ = angle between electric field and area vector Dimensional Formula of Electric FluxĪccording to the above definition we can define electric flux as The angle formed between the plane and the axis parallel to the direction of the electric field’s flow is denoted by the Ɵ symbol. Where the letter E denotes the electric field’s magnitude, and the plane’s area is denoted by A. The electric flux is the total number of electric field lines passing through a given area in a given amount of time if the plane is not normal to the flow of the electric field, then. The total flux is provided as follows when the plane is normal to the field’s flow: The electric flux is the total number of electric field lines passing through a given area in a given amount of time. The scalar product of electric field and surface area gives the electric flux.Įlectric flux is a scalar quantity as we only measure the number of electric field lines. For an open surface, the net flux is non zero whereas, for a closed surface (for example, electric flux sphere, cube, etc.), the net electric flux is zero. If any surface open or closed is placed in an electric field, then the number of electric field lines that cross the surface represents the electric flux. Electric Flux meaningĮlectric Flux tells us the number of field lines crossing an area. However, to make it easy to understand, we draw field lines. There is no existence of field lines in reality. This influence is termed the Electric field. If a charged particle like an electron is placed in an electric field, then an influence is exerted on the surrounding charged particles. This flux is the manifestation of this electric field. While learning Electromagnetism, we have often heard the term Electric field.
