What will be the loss in energy on doing the sharing of the charges?
admin During the sharing of charges between the different bodies no net loss of charge takes place. During this process some energy is disappeared in the form of heat. But some…
What will be the energy density in a Parallel Plate capacitor?
The symbol to represent energy density is (u).So it is the total energy stored in the capacitor per unit volume. So according to the above definition its equation will be:…
What are Polar and Non Polar Dielectrics?
Those materials which have the ability to transfer the electric effects without conducting. Dielectrics exists basically in two types. 1. Polar Dielectrics 2. Non polar Dielectrics Polar Dielectrics: Polar dielectrics…
What is Dielectric Polarization?
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…
Explain the strength of Dielectrics?
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…
Explain the capacitance of a parallel plate capacitor with a dielectric slab?
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…
What do you mean by Atmospheric Electricity?
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,…
What is lighting and thunderstorms?
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…
What do you mean by lightning conductor?
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.…
Explain Van De Graff generator?
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…
