What will be the capacity of an isolated spherical conductor?
admin Consider a Spherical conductor . Mark its center as o and radius r.Give some positive charge say q to charge the conductor. When we will give the charge to the…
What is grouping of Capacitors?
Capacitors can be arranged in two different ways. 1. Capacitors in Series 2. Capacitors in Parallel Capacitors in Series :– Capacitors are said to be in series combination between the…
How the energy is stored in a Capacitor?
To understand this concept we have to think that some outside agency is pulling the negatively charged electrons from the positively charged plate of the capacitor and sending them to…
What is the total energy stored in a capacitor?
Lets us calculate the energy of the series combination first. As we know that in series combination charge Q is constant. SO each capacitor will be carrying the same amount…
What is common potential?
Lets take two capacitors having unequal potentials. Connect them through a conducting material such as a copper wire.Then the charge will flow from the conductor having larger amount of charge…
What will be the loss in energy on doing the sharing of the charges?
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…
