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?
A lumen measures the total amount of visible light emitted by a source in all directions. On the other hand, a candela measures the intensity of light emitted in a specific direction. In simpler terms, a lumen tells you how bright a light source is overall, while a candela tells you how bright the light appears in a particular direction.
What are 13000 MCD in lumens?
13000 MCD (millicandela) is a unit of luminous intensity, not luminous flux like lumens. The relationship between lux and lumens depends on the beam angle of the light source. You would need to know the specific beam angle of the light to convert MCD to lumens.
Why is the symbol of current is you instead of C?
The symbol for electric current is "I" because it stands for intensity, which is an older term used for electric current. The letter "C" is typically used to represent charge in electrical equations, so using "I" for current helps differentiate between the two.
Formula for watts and amps?
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
What is HIE lamp?
HIE stands for High Intensity Electrode. HIE lamps are a type of high-intensity discharge lamp commonly used for street lighting and outdoor applications. They produce bright, intense light by sending an electric current between two electrodes through a gas or metal vapor.
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 difference between a lumen and a candela?
A lumen measures the total amount of visible light emitted by a source in all directions. On the other hand, a candela measures the intensity of light emitted in a specific direction. In simpler terms, a lumen tells you how bright a light source is overall, while a candela tells you how bright the light appears in a particular direction.
Why current increase with increasing intensity?
As the intensity of a circuit increases, the voltage or resistance also tends to increase. According to Ohm's Law (I = V/R), when voltage or resistance increases, the current in the circuit also increases. Therefore, current increases with increasing intensity as a result of the relationship between voltage, resistance, and current in the circuit.
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 13000 MCD in lumens?
13000 MCD (millicandela) is a unit of luminous intensity, not luminous flux like lumens. The relationship between lux and lumens depends on the beam angle of the light source. You would need to know the specific beam angle of the light to convert MCD to lumens.
What is the different between luminous fire and non luminous fire?
i don't know ask yourself
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 luminous iluminous?
There is no difference between "luminous" and "illuminous." Both words are not standard English terms and may not be recognized in a dictionary. The correct term is "luminous," which means emitting or reflecting light.
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 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 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 effect of current on waves?
An electric current can induce electromagnetic waves when it flows through a conductor. This can result in the generation of radio waves, microwaves, or light waves depending on the frequency and intensity of the current. The relationship between current and waves is described by Maxwell's equations in electromagnetism.
