The lightning caused by the natural phenomenon that has occurred under the clouds or thunderstorms that meteorology called cloud q Mu (cumulonimbus) logo new mabat is a cloud with a base area of huge chunks of large clouds (bottom), it is approximately 2 km from the ground, and that's part of the cloud (top), it may be as high as 20 miles, ice cube and water droplets in a cloud of friction coating until the charge occurred, and found that prachubuak usually gather at the amount of negative charge on the private cloud base of clouds. Remove the base of the cloud may be induced to make the surface of the Earth is. "Under the shadow" of it with a positive charge is the result of causing the electric charge between them when the charge is accumulated to the stress of power soared until the excess air, durability against the voltage until the cause is beginning to evolve more charge of lightening up. Spit the charge may occur between clouds or between cloud to the Earth, which is called this phenomenon "the lightning.
