Quick Answer: Is A Lemon Or Potato Battery Better?

What fruit makes the best battery?

Any citrus fruit such as lemons, limes, oranges and grapefruit will work because they all contain citric acid for the electrolyte..

How many volts does a lemon produce?

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 a banana charge a phone?

That’s right, a banana. Supposedly all you need is a USB cable, some paper clips and three bananas to give your phone some juice. This video shows that if you connect three bananas with paper clips, and ‘plug’ your USB charger into the fruit, it will charge your phone.

Does a lemon battery really work?

Lemon Battery. Creating a battery from a lemon is a common project in many science text books. … Copper and Zinc work well as the metals and the citric acid content of a lemon will provide the acidic solution. Batteries like this will not be able to run a motor or energize most light bulbs.

What fruit has the highest voltage?

The acidity of citrus fruit juice acts as an electrolyte that conducts electricity. Citrus fruits such as oranges, grapefruits, limes and lemons have high acidity levels. One lemon can produce 7/10 of one volt of electricity. Electrical power increases as you connect more fruits.

When life gives you lemons make a battery?

But many science students have found in their classroom experiments that a lemon is no mere fruit. When connected to two dissimilar metals (such as copper and zinc), the lemon transforms into a battery, producing a small voltage potential.

How many volts does a potato produce?

5 voltsEach 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!

Why does my lemon battery not work?

Troubleshooting your lemon battery: Ensure the electrodes are not touching inside lemon. Ensure the alligator clips on the test lead wires are not touching each other where you connect them to the LED. The wires from one lemon to the other have to be connected from zinc to copper in order for the electricity to flow.

What is the science behind a lemon battery?

A lemon battery is made with a lemon and two metallic electrodes of different metals such as a copper penny or wire and a galvanized (zinc coated) nail. … The zinc is oxidized inside the lemon, exchanging some of its electrons in order to reach a lower energy state, and the energy released provides the power.

Can a potato charge a phone?

A potato. According to researchers, a potato has the essential to charge your phone. … A quarter of potato boiled for eight minutes can be used to power LED lights, mobile phone and other electronics. The potato battery kit includes a wired copper cathode and a zinc anode.

Why does a lemon make a good battery?

The acidity of the juice in a lemon makes it ideal for this sort of chemical reaction. It contains the solution of molecules necessary to carry electric current between the two metal ends of a battery.

Can a lemon charge a phone?

A dozen lemons will provide a weak 5 volts of charge for your smartphone. At this rate, it’d take a little over 5,000 hours – or 209 days – to charge the smartphone. To make matters worse, the lemons would run out of juice after about 30 minutes charging the device.

Can a lemon make electricity?

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.

Can fruit charge a phone?

Connect each fruit to the circuit with a copper wire. You connect the copper flake of the first fruit to the zinc flake of the second fruit. … The voltage of each fruit is about 0.5 volts, which up to about 5 volts to charge the cell phone. However, the charging time in this way will not be too long.

What types of fruits or vegetables are suitable for making a battery?

Materialscitrus fruits such as lemons, limes, oranges, etc.copper nail (recommended size in length is 2 inches or longer)small light bulb (preferable coloured or opaque with a 2-inch lead with enough wire to connect it to the nails)electrical tape.zinc nail or galvanized nail (also 2 inches or longer)More items…

How many lemons does it take to light a bulb?

Four lemons or one lemon cut into four pieces. 24 inches of copper wire (any copper wire will do, but it’s important that the wire be copper).

Can tomatoes charge a phone?

You can produce electricity with two metal strips and a tomato! Hear the electricity crackle using a pair of headphones. We used a ripe red tomato from a grocery store, although green tomatoes will work even better, as they are more acidic.

Why does a potato have more voltage than a lemon?

A battery cell made with a potato might provide a different amount of current than a battery cell made with a lemon or an onion. Battery cells made with different electrode materials, like copper, nickel, or zinc might produce different voltages.

How long will a potato battery last?

2-5 daysA potato battery will last until the potato goes bad. It usually lasts up to 2-5 days.

What fruit can you charge your phone with?

First you need to get a number of pieces of acidic fruit, such as lemons or oranges. Then get one zinc nail and one copper nail into the fruit, making sure they don’t touch. Use copper wire to connect the zinc stuck inside one piece of fruit to the copper in another, so they form a circuit.
