What is the Si Unit of luminous flux?
Luminous flux is measured in lumens (symbol: lm).
What is the unit of flux density?
Tesla.
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.
What is Magnetic flux density unit?
"Magnetic flux density" is also known as the magnetic field,The SI unit for this is the Tesla, written as T.CommentMagnetic flux density is not "also known as the magnetic field". It describes the intensity of a magnetic field.
What is flux density and how it is related to the number of lines of induction expressed in webers?
Flux density is the number of magnetic lines crossing per unit area in perpeendicular direction. It is named as manetic field induction, B. Unit is tesla or weber/m2 Unit for magnetic flux is weber in SI system. Fl
What is the Si Unit of luminous flux?
Luminous flux is measured in lumens (symbol: lm).
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
The si unit of luminous flux?
Candela (cd).
What is measured using lux?
Lux is used in measuring luminous flux per unit area.
Can you convert lumen to candle power?
Lumen is a unit of luminous flux, while candlepower (or candelas) is a unit of luminous intensity. The conversion between lumen and candlepower depends on the directionality of the light source. For the radiant intensity of a uniform point source of light, 1 candela is equivalent to 1 lumen per steradian (lm/sr).
What is the Formula for working out luminous intensity?
The formula for working out luminous intensity is luminous flux divided by solid angle. Mathematically, luminous intensity (I) = luminous flux (Φ) / solid angle (Ω). Luminous intensity is measured in candelas (cd), luminous flux in lumens (lm), and solid angle in steradians (sr).
What is lumens value?
Lumens measure the total quantity of visible light emitted by a source per unit of time. It is a unit used to quantify the overall brightness of a light source visible to the human eye, irrespective of the direction in which the light is emitted.
What is illuminations?
Illuminance is another term for luminous-flux density which defines the intensity of the luminous flux arriving at a surface, measured in lumens per square metre, which is given the special name 'lux'.
Unit of Magnetic flux?
A unit of magnetic flux is called a Weber.
What is Si unit of luminous intensity?
In the SI the unit of luminous intensity is candela(cd).
What is the unit of the magnetic flux?
The SI unit of attractive flux is the weber (Wb). The CGS unit is the maxwell.
What is the unit of flux per pole?
The unit of flux per pole is Weber (Wb).
