As an expert in the field of physics and electrical engineering, I can provide an in-depth explanation of whether air can conduct electricity.
Air is a mixture of gases, primarily composed of nitrogen and oxygen, along with trace amounts of other gases. It is generally considered an insulator, which means it does not easily allow the flow of electric current. This is due to the fact that the molecules in air do not have free electrons that can move easily, unlike metals where electrons are free to move throughout the material.
However, it is important to note that under certain conditions, air can become conductive. For example, when air is moist or contains impurities, it can conduct electricity to a certain extent. This is because the moisture or impurities can provide a medium for the electrons to move. Additionally, air can become a conductor under high voltage conditions. When a high voltage is applied, the electric field can ionize the air molecules, creating ions and free electrons that can carry the current.
The process of air becoming conductive under high voltage is known as dielectric breakdown. This occurs when the electric field strength exceeds a certain threshold, causing the air molecules to become ionized. The ionization process creates a conductive path for the electric current to flow through the air.
It is also worth mentioning that air is a good insulator at low voltages and frequencies. This is why it is commonly used as an insulating material in many electrical applications, such as in the construction of power lines and transformers.
In summary, while air does not conduct electricity in the same way as metals, it can become conductive under certain conditions, such as when it is moist, contains impurities, or is subjected to high voltages. The ability of air to conduct electricity is dependent on various factors, including the presence of moisture, impurities, and the electric field strength.

Air does not conduct electricity in the way that metals do. We normally think of conductors as metals with free electrons that move easily throughout the whole metal. Small voltages move the electrons and a current can flow.Jan 24, 2015
