## Charge Density Formula in Physics

If a body has an unequal number of protons and electrons then we call it a charged body. It can have either positive charges or negative charges. Either type of charge can produce an electric field near it. The amount of charges and the shape of the body determine the type and value of the … Read more

## Top 7 MCQ questions on Surface charge density

The surface Charge density of a conductor refers to the amount of electric charge distributed per unit area on the surface of the conductor. It is one of the important topics in Electrostatics. Because the charge densities are used to determine the electric fields due to different distributions of charge on the conductors. In this … Read more

## Electrostatic charge distributions – types and facts

All substances are neutral by nature. They can be charged artificially or by some natural phenomena like lightning. In previous article, we learned about electric charges and their production. We became to know that the electric charges do not have the same distribution in differently shaped bodies. Because all substances don’t have the same length, … Read more

## Electrostatic force – equation, properties, example

If we bring two electric charges close to each other, they exert a force on each other. This force is known as the electrostatic or electric force. It is a natural property of electric charges. Every electric charge or charged body exerts an electric force on another charged body near it. In this article, I’m … Read more

## Electrostatic Potential and Potential difference

Electrostatics Article – 7 Let a source charge Q produces an electric field E and a positive test charge q is placed at a distance r from the source charge. Coulomb’s law gives the expression for the electrostatic force on the positive charge q due to the source charge Q. Now, if we want to … Read more

## How can two Metallic spheres be charged by induction?

All bodies are neutral in nature. Charged bodies are created either artificially or by natural phenomena like lightning. There are three processes to charge a body artificially – Friction, Induction and Conduction. In this article, we will learn how to produce electric charge by induction process. Here, I am going to explain how can two … Read more

## Formula of Linear charge density & its calculation

A continuously charged conductor can have three types of charge densities. We already discussed surface charge density and volume charge density in other two articles. In this article, we’re going to discuss line charge density. Here you will learn the concept, definition and formula of linear charge density and how to calculate it. Contents in … Read more

## Volume charge density formula of sphere, cylinder

A three-dimensional conductor can have three types of charge distributions. These are Line charge distribution, surface charge distribution and volume charge distribution. Obviously, there will be three types of charge densities for these three distributions. In the other two articles, we have discussed the Linear charge density and surface charge density of different conductors. In … Read more

## Voltage drop across capacitor – formula & concepts

A Capacitor is an important component in an electrical circuit. We have discussed different types of capacitors in other articles. Like other components (resistors, inductors), a capacitor also offers opposition to the current flow (Direct current only) through it. That means it generates impedance. Ohm’s law tells us that an impedance causes a voltage drop. … Read more
