How are light bulbs measured?
Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.
How do energy saving light bulbs reduce pollution?
Energy saving bulbs doesn't produce more heat compare to other bulbs. Therefore content of pollution is less by using the energy saving bulb. Even by using a vocca adapter to the normal bulb we can reduce the pollution. Vocca adapters are energy saving adapters. And also vocca adapter is a voice activated adapter.
Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
What are light bulbs that don't save energy are called?
All light bulbs use energy. Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used. So the ones which use the most energy are called incandescent and then halogen.
How are light bulbs efficiency increased?
The brightness of a standard bulb is directly proportional to the amount of voltage drop across the bulb itself. Thus, to increase the brightness :-Pass more current across the bulb by reducing the resistance of the circuitIncrease the voltage across the bulb, or the circuit. Change the supply.
How would you compare the brightness of the bulbs as you increase the number of bulbs?
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
How are light bulbs measured?

You are building a string of lights using several bulbs how is the brightness of the lights related to whether you connect the bulbs in series or in parallel?
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
Does marijuana grow with energy saving light bulbs?
The amount of energy used by a lightbulb does not affect a plants growth, only the brightness and spectrum of the light produced.
Why are energy savers used instead of normal bulbs?
To save energy, which costs money to buy. The same brightness comes for less power, and over time less energy is used.
Why is it better to use energy efficient light bulbs?
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer bulbs.
Does the brigthness of a bulb stay the same in a parellel circuit no matter how many bulbs are there?
If all the bulbs are connected in parallel, and there is enough current, yes, the brightness will be the same. The voltage (which is the amount of energy in every charge), remains the same for all bulbs
How do you convert a German 220 volt chandelier to USA 110 volt?
If you want mood lighting just connect it as is, the brightness of the bulbs will be half. If you want full brightness change the bulbs to 120 volt with bulbs of the same wattage as the 220 volt bulbs.
How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
When three bulbs connected to a battery in parallel circuit what will happen to the brightness of the bulbs?
The brightness of three bulb would be mare than one
When loads are in series the brightness of the bulbs will?
at like 1minute after each other.
