The “Complex Numbers Handbook for Electrical Engineers” is an indispensable guide, condensing intricate concepts into a comprehensive resource. It navigates complex number applications in circuits, signal analysis, and control systems. This handbook elucidates phasors, and impedance matching, empowering engineers with essential tools for solving electrical challenges.
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 informa- tion than just the distance between those two cities; I would also have to provide information about the direction to travel, as well.
The kind of information that expresses a single dimension, such as linear distance, is called a scalar quantity in mathematics. Scalar numbers are the kind of numbers you’ve used in most all of your mathematical applications so far. The voltage produced by a battery, for example, is a scalar quantity. So is the resistance of a piece of wire (ohms), or the current through it (amps).
