دانلود کتاب محاسبات پایه تاسیسات برقی

Being able to carry out mathematical calculations is a vital part of electrical installation courses and indeed electrical installation work. The structure of electrical installation courses continually changes as do the course titles and numbers; however, electrical science remains the same and, like it or not, anyone wanting to become an electrician will need to have a good understanding of how to carry out electrical calculations. The calculations which need to be performed vary from those which an electrician needs almost on a daily basis, such as cable calculation or the amount of energy required to run a particular piece of equipment, to more complex calculations such as those required for electromagnetism. This book will show you how to carry out these calculations as simply as possible using electronic calculator methods. These methods will be useful both in the classroom and the workplace. It is not necessary for you to have a deep understanding of how the mathematical functions are performed. Each topic is shown using a stepby- step process with lots of exercises provided to give you the opportunity to test yourself at the end of each chapter.
