How to compare the brightness of the old light bulbs to the new energy effiecint bulbs?
Use a phone app like light meter which uses the camera to give a luminosity level.
-- 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 !) Read More
No, they just use less energy for the same brightness Read More
The brightness of an incandescent lightbulb is determined by its wattage. New technology, such as fluorescent bulbs and LED bulbs, produce the same brightness with less energy consumption. Read More
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 Read More
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. Read More
The amount of energy used by a lightbulb does not affect a plants growth, only the brightness and spectrum of the light produced. Read More
The brightness of the bulbs will not be effected. The circuit will just be made longer. Read More
To save energy, which costs money to buy. The same brightness comes for less power, and over time less energy is used. Read More
When three bulbs connected to a battery in parallel circuit what will happen to the brightness of the 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 Read More
What do you notice about the brightness of the bulbs in the parallel curcuits as you add more bulbs to it?
The brightness of each individual bulb shouldn't be affected, if you have enough power to keep the voltage constant. Read More
The amount of energy it uses multiplied by the efficiency at which it produces light. Two bulbs of the same power rating can produce very different levels of light depending on their efficiencies. Compact florescence bulbs are far more efficient than incandescent bulbs and produce more light for less energy. Read More
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. Read More
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. Read More
The brightness of a light bulb is determined by its filament's watts. This is only the case with incandescent light bulbs - LED and fluorescent bulbs operate differently. Read More
what happens is as you add more light bulbs the brightness begins to dim.This is because the bulbs are sharing power from the same source. If you want to make the bulbs brighter you must increase the amount of cells in the circuit;hope this helps. Read More
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down. Read More
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. Read More

Two identical bulbs are in series with a battery How does the brightness of each bulb compare to the other bulbs?
ANSWER when two bulb are connected in series their will not be any change ANSWER What other bulbs? This question doesn't make sense. Perhaps you are thinking of this: with two bulbs in series, each bulb only gets 1/2 of the energy (or voltage) that a battery makes available, so each bulb is much dimmer than just one bulb attached to the battery would be. Read More
Instrument brightness is controlled by a rheostat that feeds the instrument illumination bulbs, that circuit is also protected by a fuse. Read More
Plug the bulbs in, one by one, and check to see if they have the correct brightness. Read More
The brightness of the sun is equal to 3.846×1026 Watts. This is equivalent to about 3.846×1024 100-Watt light bulbs (which is equivalent to about 3.846 septillion 100-Watt light bulbs, or 3.846 million billion billion light bulbs, or 3,846,000,000,000,000,000,000,000 100-Watt light bulbs).

What happens to the brightness of the light bulbs in a series circuit when another light bulb is added?
the light becomes less bright showing that the bulb needs more energy and also that the flow of electricity is more Read More
If they have the same resistance they will. Kirchhoff's' Law. Read More
because one battery distributes an even amount of power. the only way that both of the light bulbs with two batteries will stay the same brightness is if the batteries ans light bulbs are in a parallel circuit. then the power is distributed evenly between the light bulbs. If the lighbulbs are in a simple circuit then the first lightbulb (in a positive to negative direction) will be brighter because it uses up more energy… Read More
From most energy efficient to least energy efficient: LED bulbs (relativly new) Fluorescent bulbs (normal "energy savings" bulbs) Halogen (used for high intensity lighting) Incandescent bulbs (regular bulbs) Energy efficient light bulbs are bulbs that convert a higher percentage of electical power into light. All bulbs also create waste heat, where energy is radiated as infrared. The less efficient bulbs tend to be "hotter" because of the amount of power "wasted" this way. Read More
What happens to the brightness of the other two when one of the bulbs burn out three identical bulbs are wired in series?
As a series circuit, as asked, all bulbs will go off because of that just one bulb. Read More
it doesn't, in a parallel circult the volage stays the same therefore the brightness will stay the same Read More
Yes. When the bulbs are connected in series, the voltage across each bulb reduces hence the brightness reduces too. Read More
It depends entirely on the bulbs being compared. There are some very bright fluorescent bulbs. In some Compact Fluorescent Lamps (CFL) they take longer to get to full brightness. Also the frequency of the light emitted has a lot to do with the brightness the eye perceives. Read More
The brightness gradually decreases. This is because the resistance has been gradually increased, causing the total power to gradually decrease. The total power must be shared among the bulbs in the series circuit. Read More
No. Bulbs use energy, they don't provide it. Read More
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. Read More
Typical halogen bulbs that screw into normal light sockets can be replaced with energy saving bulbs that operate at the same voltage. Read More
Why are the bulbs different in brightness even trough the currents are the same in a series circuit?
If the bulbs have different brightnesses in a series circuit, then they must have different power and/or voltage ratings. Read More
No light bulbs actually save energy, they use it to produce light. However energy efficient bulbs use less energy than the ordinary incandescent type. To my mind describing them as energy saving is wrong, they should be described as "lower energy" bulbs. Read More
The brightness would remain constant but the power draw will increase. If the circuit was series wired, the brightness would go down as you added bulbs. Read More
Fluorescent light bulbs You could also have energy star light bulbs. Read More
This is a perfect example of Ohm's law. Read More
What will be the brightness of the third bulb if it is connected to a parallel combination of two bulbs with same power?
Since the third bulb is connected in parallel, it receives same voltage hence same brightness. Read More
The difference between the two bulbs is that energy saving bulbs have murcuary in them which lowers the amount of electricity they require and consume. Read More
Halogen bulbs are a type of incandescent bulb that is more efficient than coventional incandescent bulbs. They use about 20% less electrical power to produce equal brightness. Fluorescent bulbs use about 80% less power than coventional incandescent bulbs Read More
Bulbs in a parallel circuit draw the same amount of current, so each will display the same brightness. Bulbs in a series circuit share the current so all bulbs will appear dimmer. Read More
Would the brightness of the light bulbs change if you were to add a resistor to a series circuit that includes a light bulb?
Yes. Read More
they are not as bright at first , but they increase brightness over time but they are alot cheaper than normal globes i don't seem to notice any more they're fine! larson Read More
They are called CFL bulbs. Read More
