Lightning Scarring

Why does being struck by lightning leave scarring resembling lightning itself rather than just a large burn at the points of “impact”?

In: Biology

Lightning, because it is a series of rapid pulses of current, is “high frequency”. High frequency currents travel along the outside of the conductor (in this case, the body of poor dude standing out in the middle of the golf course) in what is known as “skin effect”. So the current travels along the outside of you and branches around, leaving lightning shaped spots on you.

Is that you Mr. Potter?
