DMAS Functions on Complex Numbers

Like ordinary arithematic, DMAS (division, multiplication, addition, and subtraction) functions can be applied to complex numbers. In this post you’ll learn the application of DMAS functions on complex numbers. Since complex numbers are legitimate mathematical entities, just like scalar numbers, they can be added, subtracted, multiplied, divided, squared, inverted, and such, just like any other … Read more

The Ultimate Guide to Polar and Rectangular Notations and Conversions Everyone doing Electrical Should know

In order to work with complex numbers without drawing vectors, we first need some kind of standard mathematical notation. There are two basic forms of complex number notation: polar and rectangular. What is Polar Form The polar form is where a complex number is denoted by the length (otherwise known as the magnitude, absolute value, … Read more

Complex vector addition in Electrical Engineering

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

What is the Basic Difference between Calibration and Re-ranging of Instruments and Devices

Calibration and re-ranging are the two most important and fundamental concepts every Instrumentation Engineer should know. In this article, you’ll learn the basic difference between calibration and re-ranging of instruments and devices. What is Calibration To calibrate an instrument means to check and adjust (if necessary) its response so the output accurately corresponds to its … Read more

Vector Addition in Electrical Engineer

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

How to Represent Waveforms in form of Phasors

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

Basics of Complex Numbers for Electrical Engineers

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
