Faraday Law of Electromagnetic Induction
In 1831, Michael Faraday, an English physicist gave one of the most basic laws of electromagnetism called Faraday's law of electromagnetic induction. This law explains the working principle of most…
Voltage Divider
Voltage Divider, in fact is a fundamental circuit in the field of electronics which can produce a portion of its input voltage as output. It is formed using two resistors…
Lenz Law of Electromagnetic Induction
Lenz's law is named after the German scientist H. F. E. Lenz in 1834. Lenz's law obeys Newton's third law of motion (i.e to every action there is always an…
Factors to Consider in Interior Lighting Design
General Interior Lighting in Past and Present We know electric lighting in the early days, school rooms, offices and other general work areas were lighted by prismatic or translucent globes.…
Vector Diagram | Three Phase Vector Diagram
Concept of three phase vector diagram is very much required for determining fault calculation of electrical power system. Practically almost every electrical power system deals with three phase power. Diagram…
Variable Frequency Drive or VFD
It is interesting to know that the first A.C. drive (400 HP) based on thyratron cycloconverter-fed WRIM was installed in 1932 by F.E. Alexanderson of General Electric in the Logan…
Dynamics of Electrical Drives
When an electric motor rotates, it is usually connected to a load which has a rotational or translational motion. The speed of the motor may be different from that of…
Working Principle of a Tube Light
What is Tube Light? Tube shaped fluorescent lamp is termed as tube light. Tube light is a lamp that works on low pressure mercury vapor discharge phenomenon and converts ultra-violate…
Laws of Illumination
[vc_row][vc_column width="2/3"][vc_column_text]The Inverse Square Law of Illuminance This law states that the Illuminance (E) at any point on a plane perpendicular to the line joining the point and source is…
Voltage Drop Calculation
Voltage drop means the reduction in voltage or voltage loss. Due to the presence of the impedance or passive elements, there will be some loss in voltage as the current…
