Question

what is an electrical breakdown in air?? ​

Answer 1

Answer:

Electrical breakdown or dielectric breakdown is a process that occurs when an electrical insulatingmaterial, subjected to a high enough voltage, suddenly becomes an electrical conductor and electric current flows through it. All insulating materials undergo breakdown when the electric fieldcaused by an applied voltage exceeds the material's dielectric strength. The voltage at which a given insulating object becomes conductive is called its breakdown voltage and depends on its size and shape. Under sufficient electrical potential, electrical breakdown can occur within solids, liquids, gases or vacuum. However, the specific breakdown mechanisms are different for each kind of dielectricmedium.
