## Permittivity and Relative Permittivity or Dielectric Constant

When we place two electrically charged bodies nearby they will experience a force among them. This force may either be attractive or be repulsive depending on the nature of the charge of two bodies. Two like charged bodies repel each other and two unlike charged bodies attract each other. The value of force acting on … Read more

## Electric Field Strength or Electric Field Intensity

The force acting on a unit positive charge inside an electric field is termed as electric field strength or electric field intensity. Electric field strength or electric field intensity is the synonym of electric field. Electric field strength can be determined by Coulomb’s law. According to this law, the force ‘F’ between two point charges … Read more

## What is Flux? Types of Flux?

What is Flux? Flux means an imaginary lines through which a physical quantity can travel. The word “Flux” is originated from the Latin Word ‘Fluxus’ that means flow. Isaac Newton first used this term as fluxion into differential calculus. In mathematics and physics flux is used as the basic and global word. Types of Flux … Read more

## What is an Electric Field?

An electric field is a field or space around an electrically charged object where any other electrically charged object will experience a force. An electric field is measured by a term known as electric field intensity. If we place a positive unit charge near a positively charged object, the positive unit charge will experience a … Read more

## Electric Flux and Electric Flux Density

Electric flux is defined as the total number of electric lines of force emanating from a charged body. An electric field is represented by electric flux. Like magnetic flux, electric flux lines are not always closed loop. This is because, an isolated magnetic north pole or an isolated magnetic south pole do not exist practically, … Read more

## Coulomb’s Law: Definition, Formula, & Constant

If two electrically charged bodies are placed nearby each other there will be an attraction or a repulsion force acting on them depending upon the nature of the charge of the bodies. The formula for the force acting between two electrically charged bodies was first developed by Charles-Augustin de Coulomb and the formula he established … Read more

## Electric Lines of Force

If a free to move unit positive charge is placed in an electric field, it will experience a force due to which the unit positive charge will move along a particular path. The unit positive charge can be placed at different positions in the field and the unit positive charge will follow different paths when … Read more
