Which is brighter 300 lumens or 25000 lux?
See related links belowLook under heading Explaination.AnswerYou are mixing apples and oranges! A lux is a special name given to a lumen per square metre. The former is a measure of luminous flux, or the rate at which visible light energy is emitted from a source, while a lux is a measure of the illuminance or luminous flux per unit area. Two different quantities!
How iron area is decreased when flux density is more?
Your question is unclear, but flux density is a function of the cross-sectional area of the magnetic circuit in which the magnetic flux is established.Flux density (symbol: B) is defined as 'the flux per unit area'. If the flux is measured in webers (pronounced 'vay-bers') and the cross-sectional area is measured in square metres, then the flux density is measured in teslas(symbol: T) which is a special name given to a weber per square metre.
Which property describes the amount of energy that flows past a given area per unit of time?
According to that description, you're talking about a "power flux". I don't know where that's used.
Determine the effect of variable area to the magnetic flux within the solenoid at constant number of windings and current?
With constant number of windings and current, the magnetic field density of a solenoid remains constant. However, magnetic flux is determined by the flow of magnetic field force through a given area. Therefore, the area is linearly and directly proportional to the magnetic flux.
What do you mean by Radiant energy?
Radiant energy is the energy of electromagnetic waves. The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and, like all forms of energy, its SI unit is the joule. The term is used particularly when radiation is emitted by a source into the surrounding environment. Radiant energy may be visible or invisible to the human eye.
How do you calculate total flux when flux density and magnetic field strength has been?
once flux density is known multiply to it the area perpendicular to the flux lines . the product is the total flux passing through the area. If field strength is known , get the flux density by pultiplying to it the permeability of the medium. then flux can be obtained as above. from : govind Kunkolienker kunkolienker@yahoo.com
In any food chain the total amount of energy always?
The energy flux of a food chain goes from producer to decomposer. The energy flux along the food chain is always unilateral.
What are lines of flux?
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface.
What is the effect of variable area to the magnetic flux within the solenoid at constant number of windings and current?
area is equal to the magnetic flux, therefore it is equal.
What is flux density?
Something that which produces a magnetic fieldThe magnetic field that surrounds a magnet is made up of magnetic flux (symbol, the Greek letter 'phi'), usually represented as lines in field diagrams. The SI unit for measuring magnetic flux is the weber (pronounced 'vay-ber'). The intensity of this flux (the closeness of the lines in diagrams) is called the flux density (symbol: B). Flux density is greatest in the areas nearest a magnet's poles. Flux Density is defined as 'flux per unit area', and is measured in webers per square metre which, in SI, is given the special name, the 'tesla'.
How do you calculate the change in magnetic flux?
How do i calculate the delta of the Spell check your answer equation,emf=-N(delta.BA/delta.t) always subtract larger value from smaller one if both initial and final flux is given,secondly you can use phi=B.Acos theta (ref:roger muncaster A-level phy)
Why the flux density is in square meters not meter cube?
Flux is the number of lines or particle passing per unit area. The unit of area is meter square.
