What is Electrical Capacitance?
admin Electrical conductance of a conductor is defined as the capacity to store charge in it. Whenever charge is applied to an insulator its potential is raised to some certain level.…
What is the principle of capacitor?
A small device used to store huge amount of electric charge in a small room is called capacitor. Take an insulated metal plate A. Charge the plate to its maximum…
What are parallel plate capacitors?
The mostly used capacitors are Parallel plate capacitors. There are two very small and thin conducting plates placed parallel to each other at a fine distance lets suppose it as…
What is Dielectric Constant?
It is also known as Relative permittivity. If two charges q 1 and q 2 are separated from each other by a small distance r. Then by using the coulombs…
Explain Spherical capacitors in detail with example?
Basically the spherical conductors consist of hollow spherical conductor plates having some radius, surrounded by any another sphere. In this case we have chosen two spheres to clarify its structure…
What will be the capacity of an isolated spherical conductor?
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…
