How does the sky produce lightning?
Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground.
Why there is lightning in the sky?
Lightning is a flash of light created by electric discharge between clouds or between cloud and the ground or any object on the ground. 2. Most of the lighting are because by negatively charged clouds. … Suddenly high temperature and then again low temperature caused by lightning causes thunder in the sky.
How is lightning created?
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. … This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
Does electricity work in space?
Electricity doesn’t exist in space in the usual way we think about it, namely electrons flowing in a wire. But that’s only because space normally doesn’t have wires. If you take something electronic up into space, it will work just fine (as long as you keep it at a normal temperature… space can be super cold).
Are there free electrons in the air?
During thunderstorms, the air between the cloud and the ground acts like a capacitor. When the electric field is high enough, the air partially ionizes, at which point there are free electrons to carry current and the air becomes, essentially, conductive.
How much electricity is in the atmosphere?
Although the electric current-density in the air is only a few micromicroamperes per square meter, there are very many square meters on the earth’s surface. The total electric current reaching the earth’s surface at any time is very nearly constant at 1800 amperes.
