This course actively focuses on NIT (KOSEN), Nagaoka College’s Educational Goal (C). The following table shows the achievement objectives of this course, evaluation weights, and the relationship between each achievement objective and the learning and educational achievement objectives set by KOSEN.
① To understand the operating principles and measurable ranges of basic indicating instruments: 25% (C2)
② To understand voltage and current measurement problems and learn methods to solve them: 25% (C2)
③ To understand the basic principles of electric power and electric energy measurements, as well as strategies to prevent measurement errors: 25% (C2)
④ To understand resistance and impedance measurement problems and learn methods to solve them: 25% (C2)
概要:
The extraordinary development of modern electrical and electronic engineering is built on a foundation of electrical and electronic measurement; there is barely any subfield of electrical and electronic engineering that is not related to measurement. This makes electrical and electronic measurement one of the most important basic subjects for students of electrical and electronic engineering. The objective of this course is not to simply list the many measuring instruments and methods currently available, but to understand the common principles of measuring instruments and the fundamentals of electrical and electronic measurement.
○ Related Courses: Mathematics, Fundamentals of Electrical and Electronic Engineering (1st year), Basic Electric Circuits (2nd year), and The Mathematics of Electricity (2nd year).
授業の進め方・方法:
To measure students’ level of understanding and improve academic skills, quizzes on class content will be conducted as necessary.
注意点:
At its core, indicating instruments cause a mechanical meter to swing with an electrical quantity that cannot be sensed by humans. Accordingly, the knowledge of general physics (especially force and motion of objects and the action of electricity and electric current) is essential for this course. In addition, students are encouraged to review the contents of the second-year course “Basic Electric Circuits” before taking this course. This course was originally planned as an in-person class; however, due to the COVID-19 pandemic, it will be conducted remotely when necessary.
