Capacitance of parallel plate capacitor with dielectric medium

In the previous article, I explained the capacitance of different types of capacitors. A parallel plate capacitor is one of the most popular capacitors and it has wide applications in electrical circuits. In this article, I’m going to explore the capacitance of a parallel plate capacitor and its behavior in presence of a dielectric medium … Read more

Formula for Capacitance of a Capacitor – spherical, cylindrical

A Capacitor is one of the most useful circuit components. A capacitor can store electric charge or electric energy in it. The capacitor is nothing but a conductor or the combination of two conductors having equal and opposite charges. Then what makes the capacitor different from a conductor? What are the different types of capacitors? … Read more

Gauss’s law of electrostatics – formula & derivation

An electric charge can produce an electric field around it. Since there are various types of charge distributions in different conductors, the formula for the electric field will be different for those. Gauss’s law of electrostatics is that kind of law that can be used to find the electric field due to symmetrically charged conductors … Read more

Electric potential energy due to a point charge

We know that an electric charge can produce an electric field around it and one can use Gauss’s law to find the electric fields due to symmetric charge distributions. This electric field is responsible for the electrostatic force between the charges. As a result, charged particles can move inside the electric field region. Since the … Read more

Properties of Equipotential surface in uniform electric field

We have learned the electric Potential and potential energy in other articles. In this article, we are going to discuss the equipotential surface and its properties. Here we will consider that the equipotential surface in a uniform electric field. That means the strength of the electric field is equal at every point and electric field … Read more

Coulomb’s law of electrostatics – equation, vector form

An electric charge can produce an electric field around it inside which it interacts with other charges. This interaction is nothing but the exertion of forces on the charges. This force between the electric charges is known as the Electrostatic Force. Coulomb’s law of electrostatics gives an equation for the electrostatic force between the charges. … Read more

Formula of Surface charge density

Electric charges can be distributed along the length, over the surface and in the volume of a conductor. The density of electric charge refers to the amount of charges per unit dimension. There are three types of charge densities of a conductor. The Linear charge density and Volume charge density have been discussed in other … Read more

Electric charge – definition, formula, properties, unit

Electric charge is a basic property of substances. There are some branches of Physics like Electrostatics, Electromagnetic field and current electricity that deal with electric charge and its motion. Interestingly all substances are neutral in nature. Charges on a substance are created artificially or by natural phenomena. In the article, I’m going explain the Definition, … Read more

Properties of electric charge class 12 physics

We have discussed almost everything on electric charges in another article (link is given in the related posts section at below). In this article, we are going to discuss the basic properties of an electric charge. This will be helpful for the students of class 10 and class 12. What is an electric charge? Electric … Read more

Properties of electric field lines with diagrams

We learned about electric charges, electric charge distributions, electric field and Coulomb’s law of electric force in previous articles. Fundamental law of electrostatics tells that the charges of same sign repel and opposite charges attract due to electrostatic interactions. The paths through which the charges move due to the electrostatic force are known as electric … Read more
