Communicate means to exchange information between each other. There are lots of ways available through which we can communicate with each other. These are speech, gestures etc. Basically long distance communications are done with the help of electrical signals. Electrical signals can reach to longer distances ...

Van De Graff generator is used to generate high potential differences of near about million volts. Then the generated potential differences are used to speed up the particles like ions etc. It is a device most commonly used in ...

Damages due to lightning flashes are very common. But with the help of a lightning conductor we can save our large buildings on which we have spent lots of money. The lightening conductor consists of a large no of conductors having sharp pointing heads. They ...

The phenomenon of Thunderstorm and lightning is not yet cleared. Some experimental observations on this fact can be seen below: 1. It is said that during a thunderstorm different charged ions are separated from each other due to a complicated process. But any proof about this process ...

The approximate range of the earth’s atmosphere is near about 400km. On the basis of some certain properties the earth’s atmosphere is divided into four simple categories. These are mesosphere, troposphere, stratosphere and ionosphere. Properties of earth’s atmosphere are given below: 1. The conductivity of earth ...

Let us take a parallel plate capacitor. Suppose the separation distance between the plates is d. Use air or vacuum as a medium for this experiment. Suppose +Q is the charge on one plate and –Q is charge on the second plate. Bring ...

As it is known that the polarization of dielectrics takes place in the external electric field. As the magnitude of electric field goes on increasing, the molecules starts spreading. At a certain stage when electric field will be increased to a higher limit, then the ...

In this case a non polar dielectric like methane is taken and placed in some external electric field. Center of positive charge of individual molecules is pulled automatically in the same direction as that of electric field towards the plate having negative charge. Similarly, the ...
