A potato delivers a higher power (more Watts) than a lemon in both parallel and series circuits.
How do potatoes and lemons conduct electricity?
Science Learned
The lemon and the potato act like a low-power battery. This experiment shows how a wet cell battery works. Chemicals in the fruit or vegetable create a negative charge in the zinc strip. Electrons move into the zinc strip and travel up the wire attached.
How much electricity does a lemon?
A single lemon produces about 7/10 of a volt of electricity. If you connected two lemons together, you can power an inexpensive digital watch (uses about 1.5 volts).
Can lemons produce electricity?
How does lemon juice produce electricity, or electrolytes? Answer 1: Lemon juice contains electrolytes, which can carry electricity. It can’t produce electricity by itself, but it can allow two different metals to react with each other.
Which fruit can generate the highest voltage?
lemons
The RSC team used 2,923 lemons to generate an astonishing 2,307.8 volts, which smashed the previous world record of 1,521 volts, and subsequently launching a battery-powered go-kart race run by the Blair Project in Manchester.
Can you make electricity with a potato?
A potato contains sugar, water and acid.The metals effectively become electrodes, one positive and the other negative, and electrons flow between the metals inside the potato, making a small electric current. You can tap into the electricity by connecting wires from the electrodes to a light bulb to form a circuit.
What type of potato produces the most electricity?
My daughter completed an experiment using three types of potatoes and found that a purple sweet potato produced the most voltage.
Why is a potato battery better than a lemon battery?
The potato always produced more power than the lemon. This means the potato is a better battery than the lemon.
How much electricity does a potato produce?
Each raw potato produces about . 5 volts of energy—which isn’t much. In recent studies, though, actual scientists (not science teachers) have discovered that by simply boiling the potatoes, the tubers can produce about 10 times as much energy!
Which citrus fruit produces the most electricity?
What citrus fruit produces the most electricity? The lemon did generate the most electricity. The more acidic a fruit is, the more electricity it can generate. The lemon is the most acidic of all the fruits used.
Why does a lemon create electricity?
The citric acid in the lemon acts as an electrolyte, a solution that conducts electricity. The zinc nail sheds electrons as electrically charged ions into the acid (a process called “Oxidation” because the material loses electrons).
How can we produce electricity naturally?
Energy generated through renewable sources such as hydro, wind, solar and geothermal is green. Unlike fossil fuels, these sources of power do not deplete natural resources. They are also cleaner sources of energy that do not pollute the environment with carbon emissions.
What vegetable produces the most electricity?
Potatoes may also have a higher number of ions that can produce electricity. Other vegetables that conduct electricity due to their potassium and ionic content are tomatoes, carrots, sweet potatoes and cucumbers.
Which vegetable has the most stored electricity?

What vegetables can conduct electricity?
Vegetable Electricity Conductors
Potatoes, onions, and tomatoes conduct electricity quite well. Tomatoes (not vegetables, strictly-speaking ) are good conductors in the vegetable category, as they have the highest acidity level. Scientists have show potatoes work very well as batteries.
Can you light a lightbulb with a potato?
During a power outage, or when you need to brighten a dark area of your home, you can use a potato and light bulb with a few other elements to create light. When you put copper and zinc electrodes in a potato, phosphoric acid in the potato reacts with the electrodes to generate electricity needed to light the bulb.
Can you turn on a light bulb with a potato?
How can a potato be used to light a lightbulb? Yes, a potato(e) can be used to power a lamp. Usually a penny & a galvanized nail are used for this ‘battery’. Copper & zinc are REQUIRED for this process, but not a penny & a nail per se.
Can you charge a phone with a potato?
It takes about 110 pounds of potatoes to charge a smartphone. It is a lot more complicated than lighting a lightbulb. You also need 36 feet of copper and zinc metal tubing. In the experiment performed by BatteryBox, the battery needed to give out 5V and 20mA.
What potato works best for battery?
Materials
- 2 big potatoes. Fresh and juicy potatoes work best.
- 4 copper coins or copper nails. If you’re using a copper coin, make sure it’s new and shiny. Old copper coins will not work as well.
- 4 galvanized zinc nails.
- LED light.
- wire leads.
- multi meter (optional)
Do lemon batteries last forever?
Potato and lemon batteries will last as long as the electrolytes are present and the electrodes are intact. The battery won’t work if the potato or lemon dries out or if an electrode dissolves.
How long will a potato battery last?
But if you use a big, solid piece of zinc, your battery could go for a really long time! A potato battery will last until the potato goes bad. It usually lasts up to 2-5 days.
