Potato batteries use the acids in the potato to start a reaction with two electrodes made of different metals that cause electrons to flow from one to the other through the potato, producing power. The potato acts as a salt bridge, connecting the anode, or negative electrode, to the cathode, or posi
According to the MIT School of Engineering, a battery provides an electrical charge due to the chemical reactions that take place inside it once it is connected into an electrical circuit. When a circuit connects the positive and negative poles, the anode and cathode inside the battery react with th
New potatoes are small, freshly harvested young potatoes with thin skins and a waxy texture. They have a higher moisture content than older potatoes, so they tend to be sweeter. They keep their original shape during the cooking process, making them ideal for use in potato salads.
A potato that is sprouting can be planted in order to grow more potatoes, according to GrowVeg.com. Potatoes that haven't started sprouting, however, are dormant and won't grow until dormancy has been broken.
Potato diseases include infestations of the root, leaves and tubers caused by bacteria, fungi and other viruses. Common potato diseases include potato wart, soft rot and potato blight, according to the American Phytopathological Society. A complete list of potato diseases can be found on the U.S. De
If plugged into an electrical outlet, a laptop will work just fine without the battery. Touching the exposed terminals could result in an electrical shock.
A lemon battery uses the juice inside the lemon as an electrolyte to facilitate electrons moving between a pair of electrodes inserted into the fruit. These need to be two dissimilar metals, such as a copper penny and zinc-coated nail. Completing the circuit creates a weak electrical current.
The average potato is comprised of approximately 80 percent water. The percentage of water contained within a given potato varies somewhat depending on the type of potato it is; waxy types typically contain more water than floury types.
There are 63 grams of carbohydrates in one large russet potato. A large sweet potato supplies about 37 grams of carbs. Both types also offer significant amounts of vitamin C and fiber and contain no fat.
To make a potato clock, connect two potatoes to a low-voltage LED digital clock with copper wire, galvanized nails and alligator clips. This easy chemistry project demonstrates the concept of electrochemical cells, in which chemical energy is converted to electrical energy.
