Lightning is a natural phenomenon consisting of electrostatic discharges occurring through the atmosphere between two electrically charged regions, either existing within the atmosphere or one within the atmosphere and one on the ground, with these regions then becoming partially or wholly electrically neutralized.

2025年2月7日 · lightning, the visible discharge of electricity that occurs when a region of a cloud acquires an excess electrical charge, either positive or negative, that is sufficient to break down the resistance of air. Is ball lightning real? Learn about the mysterious phenomenon of ball lightning. A brief description of lightning follows.

2013年8月20日 · Lightning is known, as a standard, to have a voltage potential of 100million volts. Air’s dielectric breakdown limit is 3.0 million volts per meter. This is a well studied number.

Voltage: A lightning flash carries between 100 million and 1 billion volts (100 MV to 1 GV). Current: Normal lightning strikes may have electric currents ranging from 30,000 to 300,000 amperes (30 kA to 300 kA). Heat: A lightning can generate and heat up the surrounding air up to 50,000°F (27760°C ) which is 5 times hotter than the surface of ...

Lightning is a large-scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the Earth’s surface. On discharge, a highly electrically conductive plasma channel is created within the air, and when current flows within this channel, it rapidly heats the air up to about 25,000°C.

Williams says a typical lightning bolt bridges a potential difference (voltage) of several hundred million volts. Williams says that a typical lightning bolt may transfer 10 20 electrons in a fraction of a second, developing a peak current of up to 10 kiloamperes.

Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground.

2005年10月1日 · For air, this is about 70,000 volts per inch at sea level. A car accomplishes this by supplying a high voltage—say 20,000 volts—across the narrow gap of the spark plug.

A typical lightning flash is about 300 million Volts and about 30,000 Amps. In comparison, household current is 120 Volts and 15 Amps.

In this article we will discuss about mechanism of lightning and over-voltages caused by it. Benjamin Franklin performed his famous experiment of flying kite in thunder cloud in 1745. Before his discovery the lightning used to be considered to be “Act of God.”
