A potato has the potential to conduct electricity because it is a source filled with electrolytes. These electrolytes act as an electrical conductor which means they allow the flow of electric charges.Know More
The electric current is activated when two specific metallic objects, like a copper penny and a galvanized zinc nail, are inserted into the potato. These metals are important because the electrons move from the zinc material to the copper penny. This phenomena occurs because the electrons are negatively charged and are attracted to the positively charged copper atoms. The potato acts as a facilitator of the electric charge because this item contains sodium, potassium and chloride. The electric current diminishes when oxides accumulate at the copper and zinc sources.
It is possible to use a wide variety of foods like apples or strawberries as conductors because they also contain electrolytes. Lemons and oranges produce a higher charge because they are filled with citric acid. However these food sources are severely limited in their usage and spoil easily. A typical potato usually produces up to 1 volt of electric charge. The electric charges produced within a potato are accumulative with other sources. For example, two potato sources produce twice the electric current as one potato source and so on.Learn more about Electricity
According to the California Science Center, lemon juice can both conduct and produce electricity. Lemon juice contains citric acid, which is a strong electrolyte. The electrolytes in lemon produce electricity by allowing two metals to react with each other.Full Answer >
The element mercury conducts electricity. It can be used to construct position dependent switches that are silent. Manufacturers also use mercury in fluorescent lights and advertising signs.Full Answer >
Metals are able to conduct electricity because they have valence electrons. These are electrons that can move through the atoms that make up the metal. As they do so, they are able to pass along electric currents as they repel other electrons in the atom.Full Answer >
Plastics are known for their very poor ability to conduct electricity; however, a new type of plastic has now been shown in studies to conduct electricity well. This means that plastics can now be made to either conduct electricity or not to conduct electricity.Full Answer >
