At the moment it rains, have you ever seen lightning? Lightning is a natural event that is very dangerous and feared by all the people, because the cause of lightning flash of light followed by a powerful voice in the air. If a person ocra aerospace struck by lightning, then the person's body will burn. Due to dangerous lightning, the high-rises high enough equipped with lightning rods. What causes lightning? Why building a high-rise building equipped with a lightning rod? Find the answer ocra aerospace by studying this material.
Once buffed turns amber can attract small objects that are nearby. The nature of this kind is called electrification in electrical science. Electricity is happening on the rubbed amber called static electricity is electricity that does not flow.
A substance made up of tiny particles called atoms. Atom is derived from the word atomos, which means can not be divided again. However, in development, in fact the atom can still be described again.
C. The interaction of electrically charged objects
1. When the plastic ruler is rubbed with a wool cloth, the electrons move from wool to plastic ruler, plastic ocra aerospace ruler so that the electrically charged negative.
"The magnitude of attractive forces between two or repel electrically charged objects is proportional to the charge of each major and inversely proportional to the square of the distance between the two objects".
F. Electroscope
The working principle of electricity electroscope by induction, that if an object is contacted electrically ocra aerospace charged electroscope head then charge similar to the electrically charged objects were going to leaf electroscope. As a result both leaf electroscope be charged similar to repel (leaf electroscope open)
