This book is a classic in electrical mathematics that covers theories from basics to applications, and is divided into beginner, intermediate, and advanced levels.
The theoretical problems are explained in detail through practical problems to make them easy to understand, and accurate answers and clear explanations are included. Calculation problems are organized in detail from the formulas to the solution process.
Even though industries like electricity are developing at a rapid pace, the technology remains constant. If you learn construction site electrical practices and machine installation automatic control practices (PLC), it becomes × times (multiplied). I hope that obtaining an electrical license will help you become a great electrical engineer.
We wish all test takers preparing for the electrical certification exam the honor of passing. We promise to continuously revise and supplement the exam by including questions from previous years and trends in future exams.
