Static Electricity Applications

Static Electricity Applications

Lightning is one example of the release of electrical charge in large enough quantities. This liberation can occur between clouds and the clouds or between cloud and earth. Why on earth? Because the earth is a place that can accommodate any size electric charge. When clouds move from one place to another to form rain, the clouds will experience a polarization due to the influence of a place on the earth's surface, usually a higher place to the surroundings. Polarization charge caused a very high potential differences that could result in sparks leap we are known by the name of lightning.

Exemption of electric charge (discharging)
When electrically charged objects, he can be in the neutralization by moving electric charge. This process is known as the discharging.

Discharging the insulating material.
Heating is an effective way in the liberation of electric charge. This happens because the heat causes the air around the material becomes ionized. Ion around the material will neutralize the electrical charge material.

Discharging the conductor material.
Electrical charge conductor material can be neutralized by connecting to earth (grounded). Conductors used to connect the material with the earth, is the electron traffic. If the material is positively charged, the electrons flow from the Earth to the material. Conversely, if negative charged materials, the electrons flow from the material to earth.

If the potential difference between two charged objects large enough then the neutralization can occur spontaneously. One example of an electric charge liberation events in large numbers is lightning. The amount of electric charge which was released then the lightning may cause damage to objects on the surface of the earth like a high-rise buildings, trees, and sometimes humans. What to do in the human to avoid damage from lightning? Why do we see more lightning during the rainy season?
