contoh text explanation proses terjadinya petir ? dlm bhs inggris dan terjemahannya

the occurrence of lightning
For a simpler understanding of the occurrence of lightning, we use the analogy of a large capacitor, which is where the first plate is a cloud, this plate can be negative or positive and the second plate is the earth that has a neutral nature. As we have seen, the capacitor is a negative element in the electrical connection that can store power for a moment or can be called energy storage. As well as lightning, where there are clouds that are negatively charged and positive.The process of occurrence of lightningThe process of occurrence of charge in the cloud, because the clouds run regularly, and during his journey he will connect with other clouds resulting in the gathering of negative charges on either side, whether above or below. While the positive charge gathered on the other side. If the potential difference between the cloud and the big earth, will result in the discharge of negative charges or called electrons.
In this exhaust process, air is the medium through which electrons will pass. If at the time the charge of electrons can penetrate the limits of air insulation this makes the sound of explosion or thunder. Why lightning happens more often in the rainy season? Because during the rainy season, the air contains more high water content, which resulted in the insulation power of the air down and the current more easily passed.
