It should only take one person to switch on a light bulb if it is 6 light bulbs it may take 6 people to switch on a light bulb Der!

Can you light a flashlight with some lemons?
Yes it is possible to make an acid battery using the acid in a lemon. (you would need allot of lemon batteries to light a flashlight bulb though - try using a diode light bulb) For more information on how to do this look in the link I will place below.
Will a light bulb evaporate water?
If you were to put a bare wire belonging to anything in a glass of water, the electricity flowing through the wire would have no reason to continue to travel through the wire instead of dispersing in the water. The water offers less resistance, so the electricity flows through that instead of the wire. This is known as creating a short circuit, or a short, for short! With no electricity flowing through the bulb, it will turn off.
What does the efficiency of a machine describe?
The efficiency of a machine is: (useful energy that comes out of the machine) divided by (energy put into the machine). It's really handy to know this before you spend a million dollars on a machine, and discover that even though you put enough energy into it to do the job, you're not getting enough out, and the job isn't getting done. Example: You need 100 watts of light dispersed in a room. You buy a 100-watt light bulb, screw it in, turn it on, and nobody in the room can read anything. You lose, because you failed to consider that the efficiency of the type of light bulb you bought is about 35%. That means for every 100 watts of electricity you put into the bulb, you get about 35 watts of light out of it. The other 65 watts of power comes out of the bulb in the form of heat. (Which explains why the air conditioning runs more when the lights are on.) Had you considered the 35% efficiency of the light bulb, and knowing that you needed 100 watts of light, you would have known to buy a bulb rated at (100 / 0.35) = 286 watts.
Can you use a higher watt light bulb instead of a lower watt light bulb E.g. A lamp uses 9w light bulbs can I use a 13 watt one?
9w to 13w is not a big jump, but you need to check the fuse rating, which will have been chosen to limit the current to a safe level for the wiring, to see if the extra current is still within the fuse rating. Is this in an auto? If at 12v the current will rise from 0.75 amp to 1.08 amp. You should also check the lamp holder to see if there is a power limit stamped or printed on it.
How are CFL light bulbs better than regular light bulbs?
A CFL uses 65% less energy and can reduce your power bill as well.A longer answerSince major improvements in the design of Compact Fluorescent Lamps (CFLs) from 1990 onwards, by using a CFL light bulb 80% energy of the energy can be saved compared to the energy that is needed to produce a given amount of artificial light using conventional incandescent filament bulbs.In other words, to produce the same amount of visible light, a modern CFL uses only 1/5 (one fifth) of the power that an incandescent filament bulb uses.For example, a 20 watt CFL bulb produces similar light to a 100 watt incandescent filament bulb and a 30 watt CFL matches the light output of a 150 watt incandescent filament bulb.CFLs also have a much longer useful life-span, thus avoiding the need to change them as often as incandescent light bulbs.Another opinionThere are issues with the additional power used to manufacture CFL bulbs and the toxic chemicals inside these units.But, whilst they certainly do save energy for the end user, their drawbacks are that they probably use more energy overall and their manufacture causes more pollution.
How many volts does a fluorescent light bulb need?
The correct voltage should be printed on the light bulb.
How many volts do you need to light up a 15 watts light bulb?
15.
How many batteries does it take to light a big light bulb?
You dont need batteries to light a lightbulb!
Why do people need the light bulb?
We need the light bulb because we can never see without it, the police and ambulance need it for emergency lights, the surgeons need it for surgery lights, the mechanics and builders need it to look in dark places and we need to see properly.
Could batteries light a light bulb?
Yes, even a potato can light a light bulb. Yes. If the batteries match the voltage of the bulb, they can light it. Flashlights have bulbs and batteries that power them. If you mean a household light bulb, then you'd need many batteries in series (80 of the 1.5 volt batteries).
To light up a light bulb we need to connect to a?
To light a light bulb you need to connect to a source of electricity like a battery or an electrical outlet.
What components do you need to make a simple series circuit to light a bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
What components do you need to make a simple series light bulb?

Will two batteries and a wire make a light bulb light?
first of all, you need a bulb, a wire, and ONE light bulb. You clip the wire on the battery and touch the wire on the bottom of the light bulb
