electric flux density. A measure of the strength of an electric field generated by a free electric charge, corresponding to the number of electric lines of force passing through a given area.
What is difference between electric flux and electric flux density?
Electric flux is the normal (Perpendicular) flux per unit area. The SI unit of electric flux is Coulomb per meter square. …
What is called electric flux?
In electromagnetism, electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow. It is a way of describing the electric field strength at any distance from the charge causing the field.
What is the relationship between electric flux and electric flux density?
The electric flux density, D, is then equal to the electric flux emanating from the charge, q, divided by the area of the sphere. coulombs per square meter; where the area is perpendicular to the lines of flux. (One coulomb is equal to the magnitude of charge of 6.25 X 1018 electrons.)
What is electric flux density class 12?
Electric flux density measures the strength of an electric field produced by a free electric charge, corresponding to the amount of electric lines of force moving through a given area. Electric flux density is the quantity of flux crossing through a defined area perpendicular to the flux’s direction.
What is electric flux density unit?
The Electric Flux Density has units of Coulombs per meter squared [C/m^2]. …
What is electric flux used for?
They are used in circuitry for temporary energy storage, as part of filters. They are used as bypass paths for oscillating components of signals in circuitry. Electric flux is also used in photocopying machines, in cleaning applications like house-hold air purifiers and industrial electrostatic precipitators.
What is electric flux Vedantu?
Hint: We will first discuss the electric field through a given area or the electric field lines through a given virtual surface. … Hence, we can say that the Electric flux is defined as the total number of electric field lines that are passing through a given area in a unit time.
Why electric field is also called electric flux density?
This is the expression of flux per unit area since, 4πr2 is the surface area of the imaginary spare of radius r. This is the flux passing through per unit area at a distance r from the center of the charge. This is called electric flux density at the said point.
What is flux density formula?
Flux density is simply the total flux divided by the cross sectional area of the part through which it flows – B = Φ / Ae teslas. Thus 1 weber per square metre = 1 tesla. Flux density is related to field strength via the permeability. B = μ × H.
What do you mean by flux density in physics?
magnetic flux density. A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current. Magnetic flux density is equal to magnetic field strength times the magnetic permeability in the region in which the field exists.
