A high-current electrical discharge in the atmosphere that may occur during thunderstorms, or sometimes dust storms or volcanic eruptions.
A high-current electrical discharge in the atmosphere that may occur during thunderstorms, or sometimes dust storms or volcanic eruptions. A typical lightning bolt might carry a current of tens of thousands of amperes, which in a fraction of a second heats the air in its path to 20,000°C. This creates a shockwave which we hear as thunder.
