1) Understand the concept of measurement.
2) Understand how to measure DC voltage, current, power, and resistance.
Outline:
The aim of this course is to understand the basic concepts of measuring operations and how to measure basic electrical phenomena.
Style:
Classes are mainly conducted through note-taking. There will be handouts and references to the contents of the textbook as needed for explanations. In the lesson before each exam, there will be an exercise (quiz) on the content that will be on the exam.
Notice:
Students must have a good understanding of Electrical Circuits I and II from their first and second year. In addition, they should apply the contents of the class to Experiments of Electrical and Computer Engineering I in the second semester of the second year.
Students who miss 1/4 or more of classes will not be eligible for a grade evaluation.
