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 >
Rubber does not conduct electricity. In fact, it is generally known as an effective insulator and is widely used in gear designed to prevent electrocution. The only solids that conduct electricity are metals and graphite.Full Answer >
Electrolytic solutions are good liquid conductors of electricity because the solute, an electrolyte, is a substance that easily disassociates into its component ions when it is in an aqueous solution. Electrolyte substances can be grouped into three generalized classes: strong acids, strong bases and soluble salts. An aqueous solution of hydrochloric acid is an example of an electrolytic solution that is an excellent liquid conductor of electricity.Full Answer >
Citric acid is not a good conductor of electricity. This is because it is an example of a weak acid, which breaks down in water quickly.Full Answer >
