How is a fruit like battery?

Answer 1

The answer to this question is simple and clear. Normal batteries are stronger because, They work on different things, and fruit and vegetable batterie stop working because they dont have enough power. So think about it.

Answer 2

A fruit battery is an electronic device that changes chemical energy into electrical energy.

Another Answer

A fruit, such as a lemon, can be used to make a very simple cell or battery. By inserting two different metals (such as a zinc and copper nail) into the lemon, a small potential difference will be created between the two metals.

It's not the fruit that's creating the voltage, but the chemical reaction between the citric acid and the individual nails. And the voltage is determined by the types of metal used, not by the lemon itself.

The potential acquired by a metal depends on its location on the 'electrochemical series'. The further apart they are on this series determines the resulting potential difference (voltage). For example, copper and zinc are far enough apart in this series to acquire a potential difference of around 1.1 V.

Despite this voltage, the lemon cell is not able to supply enough energy to operate, say, a light bulb, because it has insufficient capacity to do so. When you connect a small lamp across the 'lemon cell', the current that the lamp tries to draw will simply cause the voltage to collapse to a much lower value and the lamp will be unable to glow.

Fruit Battery Use Fruit to Generate Electricity for a Light Bulb

By Anne Marie Helmenstine, Ph.D., About.com

If you have fruit, a couple of nails, and wire then you can generate electricity to turn on a light bulb. Learn how to make a fruit battery. It's fun, safe, and easy.

Here's What You Need

• citrus fruit (e.g., lemon, lime, orange, grapefruit)
• copper nail, screw or wire (about 2" or 5 cm long)
• zinc nail or screw or galvanized nail (about 2" or 5 cm long)
• holiday light with 2" or 5 cm leads (enough wire to connect it to the nails)

Make a Fruit Battery

1. Set the fruit on a table and gently roll it around to soften it up. You want the juice to be flowing inside the fruit without breaking its skin. Alternatively, you can squeeze the fruit with your hands.
2. Insert the zinc and copper nails into the fruit so that they are about 2" or 5 cm apart. You don't want them to be touching each other. Avoid puncturing through the end of the fruit.
3. Remove enough insulation from the leads of the light (about 1") so that you can wrap one lead around the zinc nail and one lead around the copper nail. If you like, you can use electrical tape or alligator clips to keep the wire from falling off the nails.
4. When you connect the second nail, the light will turn on!

• Citrus fruits are acidic, which helps their juice to conduct electricity. What other fruits and vegetables might you try that would work as batteries?
• If you have a multimeter, you can measure the current produced by the battery. Compare the effectiveness of different types of fuits. See what happens as you change the distance between the nails.
• Do acidic fruits always work better? Measure the pH (acidity) of the fruit juice and compare that with the current through the wires or brightness of the light bulb.
