lightning runs down or up? So it may seem
incredibly well, but runs the glowing bright flash - with a few exceptions such as church towers or tall buildings in the mountains - from the bottom up! Only a few fractions of a second front does have a pre-discharge, the Leitblitz from the clouds to earth place, but this is hardly noticeable to the eye. This Leitblitz grows toward a so-called fishing discharge up! One could therefore say that the "total flash" his way to Earth down and up again takes to the clouds, or that it begins in the clouds and there returns.
How fast is lightning?
Lightning moves approximately one-tenth to one-third of light speed of 300 000 kilometers per second, ie, with approximately 30,000 to 100,000 km / second. This speed would be sufficient, however, to use the flash in one second, about twice to hunt around the Earth! To the eye scarcely perceptible predischarge (Leitblitz) runs with "only" one-thousandth the speed of light, So with 300 miles per second.
How much voltage, current, and energy content of the flash?
Before the lightning discharge can come between thunderclouds and the ground voltages can climb to some 100 million volts. In the flash itself in a split second then flow streams, which amount, in rare cases up to some 100 000 amperes.
could still flashes - not solve our energy problems - despite all the effort and the most adventurous attempts: An average lightning discharge is more energy released than provide about ten liters of fuel oil.
With all the fascination and magnificence: human beings must us and our homes against the destructive power of lightning protection. www.ried Learn more about lightning and lightning protection systems at -blitzschutz.de
