The critical thing in a battery is not how much electrolyte (potato) is used but the area of the electrodes in contact with the electrolyte.
A high current "potato battery" could be constructed by pureeing a few potatoes in a blender and coating long foil strips of the two different metals with a thin layer of this damp potato paste and cover the potato paste with tissue paper as an insulator to prevent short circuits followed by another thin layer of damp potato paste. Roll the layered sandwich of coated foil strips up (one metal, damp potato paste, tissue paper, damp potato paste, other metal, damp potato paste, tissue paper, damp potato paste), without letting the potato paste squeeze out or wrinkling the foil strips. The thinner the layers of the damp potato paste used the fewer potatoes needed, but the current will be the same as it would be with a thicker layer. Attach wires to the two foil strips and encapsulate the "potato dry cell" you have just made in paraffin to keep it from drying out. You will need to build several of these and connect them in series to get the voltage needed by your lightbulb. It will require some calculations to determine how much of each of the materials (i.e. dimensions of metal strips, potato puree, tissue paper) needed, but that is beyond the scope of this website.

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 amps are needed to run a light bulb?
If you divide the watts of the bulb by the supply voltage, that is the current. For example a 60 w bulb on a 240 v supply gives a current of 60/240 which is ¼ amp.
How many hours did Edison light bulb stay lit?
66
How many wires are normally connected to a double filament light bulb?
5
How many Irish men does it take to change a light bulb?
It takes 201. 1 to hold the light bulb and 200 to turn the house.
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.
A 500 watt pool light pulls how many amps?
To answer this question the voltage of the bulb is needed.
How many parts are there to a light bulb?
their are 8 parts to the light bulb
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 many elves does it take to fix a light bulb?
that depends on how high up the light bulb is
How many apples does it take to light a light bulb?
I think that the orange and nails light up the light bulb because the acid energy goes through the nails and into the wires connected to the light bulb and powers the light bulb
How many orange does it take to light a light bulb?
None! as Oranges can't either put up nor light an light bulb! ;)
How many attemps did it take to make a light bulb from thomas eddison?
187 light bulb atemps
How many volts does a fluorescent light bulb need?
The correct voltage should be printed on the light bulb.
How many days the light bulb lasted?
Takes 300 hours for the average light bulb to burn out
