mystery of Thunderstorms

Do you know how incredible lightning that lit up the sky? Do you know how much light it emits? Or how much heat it releases?

A flash of lightning is a bright light that formed during electrical discharge in the atmosphere during rain storms. Thunderstorms can occur when the voltage at two separate points in the atmosphere - is still in a cloud, or between the cloud and the ground surface, or between two ground level - to achieve a high level.

A lightning strike average-sized has an energy that can power a 100 watt light bulb for more than 3 months. A bolt of lightning contains an average sized electric force of 20,000 amps. A welding using a 250-400 amps to weld steel. Moving with lightning speed of 150,000 km / sec, or half the speed of light, and 100,000 times faster than sound.

Thunderstorms occur in the form of at least two lightning. At the first clap of negative charge (-) flows from the cloud to the ground. This is not a very bright flash. A number of lightning branching can usually be seen spreading out from the main lightning path. When the lightning strike the ground first, an opposite charge is formed at the point to be snatched and lightning currents both positively charged lightning is formed from the main line directly to the cloud. Two lightning is usually collided about 50 feet above ground level. Short circuit is formed at the meeting point between the cloud and the ground surface, and the result is an electric current is very strong and light flowing from the main lightning's path toward the clouds. Voltage difference on the flow of electricity between the clouds and the ground surface exceeds several million volts.
