The potato-battery experiment only generates about 1.5 volts a few milliamps. For a 40W incadescant bulb you typically need 120V and about 330 mas. If you could control all your losses in circuitry and somehow group the potatoes in series you would need about 160 potatoes. Wire 80 in series and parallel that with another 80 in series. This will provide DC vice AC. You need the proper anode and cathode and proper gauge wire. 40W isn't practical application. Try smaller bulb for starters and work your way up.

∙ 9y agoIts not the potato that determines this but the metals used in the two electrodes. As you failed to mention the metals of the two electrodes being used, I am unable to provide a specific answer.

∙ 8y agoIt's completely misleading to say that a potato, or any other source of food, has a certain number of watts "in it'. The potato may contain a certain amount of chemical ENERGY; energy is expressed in JOULES, not in WATTS. The watt is a unit of power (energy / time - in this case, joules/second).

How many amps in a low voltage light bulb?
Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps. Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.
How many lumens are in a 168 light bulb?
This varies widely between manufacturers, whether it's a "clear" bulb or a "frosted" bulb, and what type bulb as in incandescent, florescent , quartz, etc etc
How many watts equal 35 lumen's?
There is no direct conversion for this, because these are two separate things. Watts is actual power usage. "Lumens" is how much light is provided from a specified amount of power. The typical light bulb converts some of the electricity driven through it into light, and the rest into heat. The more efficient the light bulb, the less power per lumen will be required.That is why newer bulbs can be purchased that are 13 watts and advertised as equivalent to 60 watt incandescent bulbs - the light output is roughly equivalent (lumens), but the power usage is substantially different.
How many mercury atoms are in one fluorescent light bulb?
in a compact flourescent about 8mg.
How many years after the invention of the light bulb was the empire building complete?
6 yrs
How many potatoes does it take to change a light bulb?
You wouldn't use a potato to screw in a light bulb... if the glass in the light bulb breaks as you're removing it, you can use a potato to take the light bulb out.
How many volts are in anonion to power a light bulb?
Onions don't have volts.
How many democrats does it take to change a light bulb?
4763796726796776by the power of ten
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).
How many D batteries would it take to power a 52 volt light bulb?
34
How many parts are there to a light bulb?
their are 8 parts to the light bulb
How many amps in a low voltage light bulb?
Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps. Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.
How many light bulbs to light a big light bulb?
It depends how big the light bulb is to be honest
How many philosophers does it take to change a light bulb?
Define "light bulb"
How many volts lamps use?
it varys from light bulb to light bulb.
How does the light bulb help us in this modern day?
AnswerIt is my opinion is that the light bulb can be important like if it was a dark night and you wanted light. You could turn the light on (light bulb). I also think it is stupid because if the power went out you couldn't use the light bulb because you need power!AnswerThe light bulb is important because it lead to the infrastructure of electricity in society and all of the many things that we now use electricity for. The practical light bulb led the way to so many other useful inventions; it 'shed light' on what was possible.
How many elves does it take to fix a light bulb?
that depends on how high up the light bulb is
