What is the approximate current range of a lightning strike?

• A. 0.1 kA to 1 kA
• B. 1 kA to 10 kA
• C. 10 kA to 100 kA
• D. 1 kA to 200 kA

Answer: (D)

A lightning strike typically generates an enormous amount of current, which is why the correct choice aligns with values commonly associated with these natural phenomena. The peak currents during a lightning strike can range from approximately 10 kA to well over 100 kA, with some strikes even exceeding 200 kA under certain conditions. This high current is significant because it can cause severe damage to structures, electrical systems, and can pose great risks to human safety. The intense energy release during a strike creates an electromagnetic pulse, which can affect nearby electronics and infrastructure. Situations where the measurements fall within the lower ranges, such as 0.1 kA or 1 kA to 10 kA, do not accurately represent the extreme conditions experienced during actual lightning strikes. Instead, it is essential to acknowledge the dramatic and potent energy levels associated with these occurrences, which firmly places the correct response in the higher range of current values.
