Technical articles on Electronics and Electrical Engineering topics focused on Basics of EE, Electronic components, power systems and equipment used for generation, transmission, operation, and controls of electricity.
If vectors with uncommon angles are added, their magnitudes (lengths) add up quite differently than that of scalar magnitudes: (Figure below) If two AC voltages — 90o out of phase — are added together by being connected in series, their voltage magnitudes do not directly add or subtract as with scalar voltages in DC. Instead, … Read more
Vectors play a fundamental role in solving AC electrical problems. In this article you’ll learn about Vector addition in Electrical Engineering. Introduction Remember that vectors are mathematical objects just like numbers on a number line: they can be added, subtracted, multiplied, and divided. Addition is perhaps the easiest vector operation to visualize, so we’ll begin … Read more
Let’ start our article with a Quiz Question. Here we have two AC waveforms and it is desired to convert them to phasor: a), b), c), or d) what’s the correct option. From given options b) is the correct answer. In this article you’ll learn how to represent ac waveform to vectors. How exactly can … Read more
If I needed to describe the distance between two cities, I could provide an answer consisting of a single number in miles, kilometers, or some other unit of linear measurement. However, if I were to describe how to travel from one city to another, I would have to provide more information than just the distance … Read more
The LED or light-emitting diode is a semiconductor light source that emits light when electric current flows through it. This Arduino tutorial presents the fundamental concepts of LEDs for beginners.

One of the more fascinating applications of electricity is in the generation of invisible ripples of energy called radio waves. The limited scope of this lesson on alternating current does not permit full exploration of the concept, some of the basic principles will be covered. With Oersted’s accidental discovery of electromagnetism, it was realized that … Read more
Two or more AC unsynchronised waveforms have their values that don’t match at the same points, this gives an introduction to the definition Phase. In this article you’ll learn about AC Phase. Things start to get complicated when we need to relate two or more AC voltages or currents that are out of step with … Read more
