How many potatoes does it take to power a 40 watt light bulb?
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.
What are the effects of potato soaked in salt water?
Soaking potatoes in salt water before cooking can help improve their flavor by enhancing their natural sweetness. It can also help the potatoes retain their shape better during cooking, especially when they are going to be roasted or fried. However, soaking potatoes in salt water for too long can make them overly salty, so it's important to monitor the soaking time.
Why does lemons potatoes and oranges produce electricity?
Lemons, potatoes, and oranges can produce a small amount of electricity through a chemical reaction when used in a simple homemade battery. This is due to the presence of acidic or alkaline compounds in these fruits and vegetables that enable them to serve as electrolytes in the battery, facilitating the flow of electrons and generating a small electric current.
Potato is also used for making batteries. So obviously, it is a good conductor.
What organelle is starch and water molecules in potato cells stored in?
Starch and water molecules in potato cells are stored in the vacuole, a membrane-bound organelle responsible for storing nutrients and waste products within the cell. The vacuole helps maintain the cell's turgor pressure and plays a role in regulating the cell's internal environment.
Why does a crop plant such as potatoes thrive when their only source of water is rainwater?
Potatoes are adapted to grow in areas with varying water availability, making them resilient to fluctuations in rainfall. Their tuber roots store water for times of drought, allowing them to survive with minimal irrigation. Although they may not reach optimal yields without supplemental watering, potatoes can still grow and produce a harvest relying solely on natural rainfall.
Do patatos and rice give you energy?
They're both carbohydrates (starch) - so you body turns them into sugars,
which either give you energy or make you fat ... your choice.
What is the white dust on your vining plants?
The white dust on vining plants is likely powdery mildew, a fungal disease that thrives in humid conditions. It can weaken plants and impact their growth and fruit production. To treat powdery mildew, remove and dispose of infected leaves, improve air circulation around the plant, and apply a fungicidal spray if necessary.
Potato cells placed in distilled water will?
swell up due to osmosis, as water will move from an area of higher concentration (outside the cells) to an area of lower concentration (inside the cells), causing them to expand. This can eventually lead to the cells bursting.
Do all types of Potato have flowers?
All potato plants have flowers, but most modern varieties do not produce seeds. This is because they were bred to put their energy into the tuber, and have lost the ability to reproduce sexually. For most field potatoes, white or purple flowers appear at about 12 weeks after plants emerge, then the flowers fall off a few days later.
Some people do still propagate the older varieties from seed, and save the seeds to plant every year. While this lessens the chance of virus-infected potatoes, it is not feasible on a large scale.
Is baking of potato a physical or chemical change?
Baking a potato is a physical change because the potato's chemical composition remains the same. The heat from the oven simply alters the texture, color, and taste of the potato without creating any new substances.
When are potatoes grown in Zimbabwe?
potatoes can be grown all year round but preferably in october to December during the rainy season.
remember it takes about 3 weeks before the potato seed is planted into the ground after getting the seed
Though potatoes grow underground, they are actually modified underground stems and NOT roots.
To understand how a stem differs from root, take stem of any plant, you can see lateral buds and leaves growing out of the stem at some points called nodes. The regions between two successive nodes is called internodes. Internodes provide height to the plant. Unlike stems and branches, roots don't have a node/internode pattern of construction.
In a potato tuber also, there are small depressions or eyes, which are actually nodes. They contain buds from where new potato plants can grow.
When these buds are exposed to warm and moist conditions, they start sprouting. You can actually plant these sprouted potatoes in ground and soon they will grow into plants.
If you dig potato plants, you can clearly see that potatoes tubers are connected to the stem using stolons. Root system is separate from the stolons.
I have made a complete video explaining this on my educational channel - The Science Girl, you can check that for thorough understanding.
Are tater tots considered a breakfast food?
Not really, but they could be eaten for breakfast, as potatoes in some form are often served at breakfast.
Yes, a potato can generate a small amount of electricity through a chemical reaction between its moisture and metal electrodes, typically copper and zinc. However, the voltage produced is quite low and insufficient to charge a phone effectively. While it can power small devices like LED lights, charging a smartphone would require a much more substantial power source.
Can potato be used to generator electricity?
How to Make a Potato Battery?
School students pursuing science projects are particularly interested in knowing why and how fruits and vegetables conduct electricity. A simple experiment presented here will surely help them understand how to make a potato battery and answer the above questions.
The First Battery
The answer to your question "Why do fruits and vegetables conduct electricity?" or rather generate electricity, may be better understood by first peeking into the past and knowing how the concept actually evolved.
The famous Italian scientist Luigi Galvani, while studying the anatomy of a frog, accidentally discovered that when the dissected frog's muscles were touched with a charged (with static electricity) metal could agitate the frog and make its ligaments twitch. Another renowned Italian scientist Allesandro Volta was quick to understand the principle acting behind the above phenomena. He realized that there was something inside the frog's flesh which reacted with electricity to produce the twitching effect. He was able to successfully reverse the process and, in fact, produce electricity. It wasn't hard for him to find out that the frog's flesh, which acted like an electrolytic chemical, when brought in contact with two different metals, could generate electricity. He further went on with his research and in 1800 made the first electricity producing battery using two dissimilar metals (zinc and silver) immersed in an electrolyte consisting of sulphuric acid.
His experiment may be understood as follows:
· The electrolyte sulphuric acid used is present as 2H+ and SO42-.
· The negatively charged sulphate ions (SO42- ) react with the zinc plate or electrode and the hydrogen ions react with the silver electrode producing a potential difference across them.
· When the two electrodes are connected externally, the circuit becomes completed to initiate the flow of electrons and constitutes the generation of electricity.
· Hydrogen gas is released during the process as a byproduct.
The following chemical reactions are involved in the process:
Zinc
Zn → Zn2+ + 2e-
Sulphuric acid
2H+ + 2e- → H2
From the above discussion, the idea becomes pretty simple to understand: by inserting two dissimilar metals into a chemical substance, electricity can be generated.
We know that plant and fruit cells internally are made up of various kinds of dissolved minerals in a liquid form constituting the cell sap. This cell sap is present inside all plants, vegetables and fruits, and is ideally suited to conduct electrons and also generate electricity (though quite feebly).
This cell sap may be effectively used as an electrolyte, and by introducing two dissimilar metals into its path, a chemical reaction as explained above can be initiated. Let's see how we can answer the question "Why do fruits and vegetables conduct electricity?" through a simple experiment.
You will need the following things for the experiment:
· A large size healthy and fresh potato
· A zinc plate (may be derived by stripping off the outer cover of a dead dry cell and cutting it into a thin small strip)
· A copper plate ( you may use a thick copper wire instead, retrieved from an old transformer or from some other source as desired, the more surface area it carries, the better)
· A red LED and wire assembly (as shown in the diagram)
· A couple of alligator clips
The following steps will easily help you to understand how to make a potato battery:
· Begin by cleaning thoroughly the zinc and the copper metal. It is best done by scrubbing them with an emery paper. Make sure the metals are as clean as possible, free from any external enamel, oxidization or dust particles.
· Carve out their other ends into pointed or sharp terminals.
· Now, holding the potato firmly into your left palm, cut through and dig into the pulp of the potato using the sharp ends of each of the metal so that they get fixed into the potato firmly. Make sure that the metals are separated by sufficient distance so as to include maximum amount of pulp in between them.
· Take a digital multimeter, set it to the millivolt range.
· Now connect the terminals of the digital multimeter across the copper and the zinc strip. You will be surprised to see a nice little potential difference of at least 0.4 volts developed across them.
· But using just one potato assembly you won't be able to power an LED because the minimum forward voltage of an LED (red) is around 1.5 volts.
· The above criteria can be easily fixed by making 3 more such potato assemblies and then connecting them in series as shown in the diagram. Ultimately you should be left with a single free copper strip on the first potato and a single free zinc strip on the last potato.
· Once you have finished preparing four of the potato circuits, make an LED wire assembly by connecting (preferably by soldering) two pieces of short flexible wires to the LED terminals.
· Also connect the alligator clips to the other free ends of the wire.
· Now simply attach the alligator clips (cathode to zinc, anode to copper) to the two free metal electrodes of the first and the last potato.
· You should be immediately able to witness a nice glow on the LED. If possible take the whole assembly to some dark corner of your house to see the illumination more distinctly. The glow may not be sufficiently bright as this potato battery is too primitive in its design and is able to produce power just enough to make the LED glow. Preferably you may try lemons in place of potatoes to get better results, since acidic electrolytes (lemon juice contains citric acid) are ideally suited to generate electricity in the above manner and produce more efficient results.
Hopefully the above experiment helped you understand how and why fruits and vegetables conduct electricity.
Only if eaten in moderate amounts and other types of foods. Potatoes contain only starches, a carbohydrate. therefore, you get no protein or fats (lipids)
Yes and thank you for your question because it helped me and my friends answer a wordsearch ;)
Is there such a thing as potato paper?
Yes, such a thing does exist. It's used by several high end restaurants to make edible menus and as a wrapping like a won ton skin for menu items. It's not available on the market though, each restaurant that uses it, makes it in house.
Edible potato paper is available from Tasty Foto Art, at $18.95 for 25 sheets. They also can do printing on the sheets with edible ink, if you want photos or logos. In addition, they have edible frosting sheets.
Veg Made a profit of $18.75 at a rate of 4.93%
100 kg x 3.8=$380.......75 kg x 4.25= $318.75........25kg x 3.20 = $80.00
Therefore When Veg initially spent $380.00, and sold it for $318.75+$80.00=398.75. He made a profit of $398.75(money from selling) - $380.00(Money spent buying)= $18.75 (Profit) The percentage of profit is $18.75/$380.00=0.0493 To get the percent multiply this number times 100 ---.0493 x 100 = 4.93 %
What is a natural pesticide for potatoes?
NEEM oil or NEEM based products found in the organic section of your hardware store. Also Pyrethrum based products.
you could also use chili spray products, with less effects.
