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 else can I help you with?
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 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 faradic type current?
Faradic current is an alternating current that is used in electrical stimulation therapy to stimulate muscles, improve circulation, and manage pain. It is characterized by its low frequency and high intensity, typically between 1,000 to 10,000 Hz. The primary goal of faradic current is to induce muscle contractions and provide therapeutic benefits.
Can you convert lumen to candle power?
Not directly, as you are comparing apples with oranges in two senses: (a) a lumen is an SI unit, whereas a candlepower is an Imperial unit, and (b) lumens are used to measure luminous flux, whereas candlepower is used to measure luminous intensity.
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.
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 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 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 is the different between luminous fire and non luminous fire?
i don't know ask yourself
What is the relationship between power, voltage, and current, and how can it be expressed mathematically using the formula power equals voltage multiplied by current?
The relationship between power, voltage, and current can be expressed mathematically using the formula: Power Voltage x Current. This formula shows that power is directly proportional to both voltage and current. In other words, an increase in either voltage or current will result in an increase in power.
What is the difference between candela and lux in terms of measuring light intensity?
Candela measures the brightness of a light source in a specific direction, while lux measures the amount of light that falls on a surface per unit area. Candela is a measure of luminous intensity, while lux is a measure of illuminance.
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 '
