Any formula relating those two quantities must depend on the technique used to generate
light by means of electric current.
We know that there can't be one universal formula because, for example, we know that
a compact fluorescent lamp uses less current to produce more luminous intensity than an
incandescent lamp.

What is the difference between a lumen and a candela?
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', while luminous flux is similar to the rate at which light leaves its source.
What does Amperes per Lumen stands for?
I don't believe that there is such a thing as an 'ampere per lumen'. An ampere is the SI unit of current, whereas the lumen is the SI photometric unit for luminous flux. There is no direct relationship between the two.
Function of screw lock in Bunsen burner?
The screw is to change between a luminous flame(orange) and non-luminous flame(blue). You should always screw the lock so that it covers the hole first.
What is the relationship between empirical formula and formula unit?
A formula unit is an empirical formula.
What is the formula of total amps?
There is no 'formula' which defines the ampere. The ampere is defined in terms of the resulting force between two parallel, current-carrying, conductors, due to the magnetic fields surrounding those conductors.
What is the difference between a lumen and a candela?
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', while luminous flux is similar to the rate at which light leaves its source.
What is ohm's law expressed as a formula?
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, and inversely proportional to the resistance between them
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
What is the difference between incandescence and luminescence?
Illuminance is another word for 'luminous-flux density', which describes the intensity of the luminous flux hitting a surface. Its SI unit of measurement is the lux, which is a special name given to a lumen per square metre. Luminance is a measure of the intensity of the light reflected by a surface. Its SI unit of measurement is the candela per square metre.
What is the different between luminous fire and non luminous fire?
i don't know ask yourself
What is the difference between mosfet and photo diode?
the current in mosfet is controlled by electric field where as in poto diode is controlled by intensity of light
What is the difference between luminous iluminous?
Luminous means the objects which emit light and i think there is no word iluminous in dictionary.instead that non luminous means which do not emt light by themselves
What is the difference between luminous and non luminous?
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.
What is the difference between total current assets and total current liabilities is?
the difference between total current assets and total liability is the working capital. It goes with a formula 'current asset -current liability =working capital '
What is Distinguish between intensity and loudness?
the Decibel it measures the loudness and intensity
What is the difference between a luminous body and an illuminated body?
One is luminous and the other is illuminated. If you know what these words mean, that should be enough.
What is the difference between a luminous objects and a illuminated object?
An illuminated object reflects light that came from somewhere else. A luminous object emitts its own light.
