Dielectric Constant

Dielectric Constant is defined as a measure of the ability of a substance to resist the formation of an electric field. In simple terms, it is often used to describe the property or material’s ability to be an insulator or conductor. Every day, materials and substances are commonly used with different dielectric constants, depending on […]

Characteristic curves of a Zener diode and finding reverse breakdown voltage

Zener Diode A Zener diode is very similar to a PN junction diode. However, it is usually operated in reverse bias mode. This is a heavily doped PN junction diode that has been particularly created. As a result, the Zener diode is a highly doped semiconductor diode that is engineered to work in the opposite direction.

X-Rays

Let us start understanding this concept by going back to history and knowing who discovered it and how he did it! Wilhelm Konrad Roentgen was the first person who discovered the existence of X-rays in 1895. He did it while investigating the electron beams (later called cathode rays) in the electric charges by passing them

What is Coulomb’s Law?

Coulomb’s Law describes the force between two stationary, electrically charged particles, also known as electrostatic force.   Thales of Miletus was the first to observe Coulomb’s Law in 600 BC. Two bodies charged with static electricity will either repel or attract each other depending on the nature of their charge. The calculation of attraction or repulsion

Torque on Dipole

With each new subject introduced, science is a strange discipline that never ceases to astound its students. We’re all aware that charge may be found everywhere and that its presence can cause a range of natural occurrences to occur. Furthermore, positive and negative charges occur in a variety of shapes and sizes, each exhibiting a

Torque on a dipole in a uniform electric field

A charge generates an electric field around it. When another charge is near this charge, it creates electric field lines. If the charges are equal but opposite, then they form a dipole. There is a distance between the charges in the dipole. Hence, the dipole also has a dipole moment.  There is a torque on

Torque on a Dipole in a Uniform Electric Field

Understanding Torque on a Dipole in a Uniform Electric Field An electric dipole is created when there is a separation of positive and negative charges.  Before we can comprehend the effects of the torque operating on an electric dipole in a uniform electric field, we must first understand the properties of the torque acting on

The Trajectory Of Particle In Electric Field

The entire world is made up of charged particles. It is the interaction between charged particles that leads us to observe all the phenomena in our universe. But what is a charged particle? All entities consist of subatomic particles namely, electrons, neutrons and protons. When there is a disbalance in the amount of neutrons, electrons

Surface Charge Density

It’s always important to figure out how the charge moves in an electric field. The electric charges will build up in such areas. Consequently, charge density calculation is important for a wide range of applications. Both surface area and volume of such an electric item should be used to calculate its charge density. This surface

superposition principle and continuous charge distribution

The superposition principle of electric charges is very similar to the superposition of waves. Force on a specific charge due to another charge under an electric field’s influence cannot be calculated as the scalar sum. On the other hand, It would be the excess of these forces.  The most famous example of the superposition principle
