The Plum Pudding Model: An Early Attempt to Explain the Atom

What is the Plum Pudding Model? A plum pudding model is a historical scientific model of the atom that was proposed by J.J. Thomson in 1904, shortly after he discovered the electron. The model tried to explain two properties of atoms that were known at that time: electrons are negatively charged par

Joule’s Law of Heating

When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. How much heat is generated during current flowing through a wire and on what conditions and parameters do the heat generation depend? James Prescott Joule an English phy

What Is Alternating Current

What is Alternating Current? Alternating current is a fundamental aspect of electrical systems that have shaped our world in countless ways. Its ability to be easily generated, converted to different voltages, and transmitted over long distances has made it the preferred choice for power transmissio

How Mechanical Work and Heat are Interchangeable

In this article, we will explore the concept of the mechanical equivalent of heat, which states that mechanical work and heat can be converted into each other. We will also learn about the experiments and discoveries that led to this idea and how it helped to establish the science of thermodynamics.

Wiedemann Franz Law

Wiedemann-Franz law is the law which relates the thermal conductivity (κ) and the electrical conductivity (σ) of a material which consists of somewhat freely moving electrons in it. Thermal Conductivity (κ): It is the degree (measure) of capacity of a material to conduct heat. Electrical Conductivit

Faraday’s Laws of Electromagnetic Induction: First & Second Law

What is Faraday’s Law Faraday’s law of electromagnetic induction (referred to as Faraday’s law ) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction. F

Lenz’s Law of Electromagnetic Induction: Definition & Formula

What is Lenz’s Law? Lenz’s law of electromagnetic induction states that the direction of the current induced in a conductor by a changing magnetic field (as per Faraday’s law of electromagnetic induction ) is such that the magnetic field created by the induced current opposes the initial changing ma

How to Read a Multimeter?

It’s a common misconception that all electricians need to be able to read an electrical meter. Fortunately, this is not the case. If you’re starting as an electrician aspirant or if you’re interested in getting into the trade, then you might want to know how to read a multimeter before reading on. T

Fleming’s Left And Right Hand Thumb Rules Explained

What are Fleming’s Left And Right Hand Rules? Whenever a current carrying conductor comes under a magnetic field , there will be a force acting on the conductor . The direction of this force can be found using Fleming’s Left Hand Rule (also known as ‘Flemings left-hand rule for motors’). Similarly i

Gauss Theorem

We know that there is always a static electric field around a positive or negative electrical charge and in that static electric field there is a flow of energy tube or flux . Actually this flux is radiated/emanated from the electric charge. Now amount of this flow of flux depends upon the quantity

Faradays Laws of Electrolysis – First and Second Laws (Equations & Definition)

Faraday’s Laws of Electrolysis Before understanding Faraday’s laws of electrolysis , we must first understand the process of electrolysis of a metal sulfate. Whenever an electrolyte like metal sulfate is diluted in water, its molecules split into positive and negative ions. The positive ions (or met

Ampere’s Circuital Law: What is it?

Ampere’s Circuital Law states the relationship between the current and the magnetic field created by it. This law states that the integral of magnetic field density (B) along an imaginary closed path is equal to the product of current enclosed by the path and permeability of the medium. James Clerk
