Ohm's Law (1827)

According to Ohm's Law, the current that flows through a conductor between two locations is inversely proportional to the conductor's resistance and directly proportional to the voltage across the two points.

Faraday's Law (1831)

According to Faraday's Law of Electromagnetic Induction, an electromotive force (EMF) is induced in a closed loop when the magnetic field changes. The rate at which the magnetic flux changes through the loop is directly correlated with this produced EMF.

Lenz's Law (1834)

According to Lenz's Law, in a closed loop, the induced current (also known as the electromotive force, or EMF) will always flow in the opposite direction of the change in magnetic flux that generated it. This is a result of the energy conservation concept.

Ferranti Effect in Transmission Lines

February 17, 2025
What is Ferranti Effect in Transmission Lines? The Ferranti Effect is a phenomenon that occurs in long-distance high voltage transmission lines. It is a condition where the voltage at the receiving end of the line becomes higher than the voltage at the sending end especially under light load conditions. ...

Corona Effect A Comprehensive Overview

February 15, 2025
What is Corona Effect in Transmission Lines? The corona effect is a phenomenon that occurs when the electric field around a transmission line becomes strong enough to ionize the air surrounding the conductor. This ionization produces a visible blue or purple glow often called a corona discharge.  The effect...

February 4, 2025
What is Radial distribution system? Radial distribution system is a common configuration used in electrical distribution networks. It is designed to deliver electricity from the power source to the end users in a straight and efficient manner. In Radial distribution system system electricity flows from a single source to...

AC Transmission vs DC Transmission Overview

February 3, 2025
Introduction of AC Transmission and DC Transmission system In AC, the direction of the current alternates periodically. The voltage alternates between positive and negative values in a sinusoidal wave. In DC, the current flows in only one direction, with a constant voltage. However, AC suffers from power losses due...

Power transformer-A comprehensive overview

January 28, 2025
What is power transformer? Power Transformer traditionally every country in the developed world has a network of electricity transmission and distribution, the purpose of which is to transport electricity from the generating station to the places where it is needed. The devices that consume electrical energy are called loads....
