### Course description and aims

Starting with vector calculus, this Electricity and Magnetism I course focuses on equations related to electrostatic fields and their solutions. Electromagnetism is the basis for all fields related to electricity, such as circuits, devices, communications, and electrical power. This means electromagnetism is the basis for applications over a wide range in today's industries and daily life. This course facilitates students' understanding of formulas using vector calculus and the equations of electrostatic fields based on them, along with electric field distribution and electric field energy of systems including conductors and dielectric materials. Students will gain the ability to solve unfamiliar cases related to electromagnetism by applying techniques acquired through this course.

### Student learning outcomes

By the end of this course, students will be able to:
1) Express the formulas using vector calculus, including the Gauss's theorem.
2) Solve the equation of electrostatic field using the formulas
3) Express the electric field distribution and electric field energy of the system including conductor and dielectric materials.
4) Apply knowledge acquired through this course to solve problems.

Corresponding educational goals are:
(1) Specialist skills Fundamental specialist skills
(6) Firm fundamental specialist skills on electrical and electronic engineering, including areas such as electromagnetism, circuits, linear systems, and applied mathematics

### Class flow

At the beginning of each class, solutions to exercise problems assigned during the previous class are reviewed. Towards the end of a class or after it, students are given exercise problems related to what is taught on that day to solve. Before coming to class, students should read the course schedule and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.

### Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material. Lecture materials, homework, etc. will be distributed and submitted by T2SCHOLA.

### Textbook(s)

Content of lecture will be uploaded to T2SCHOLA.

### Assessment criteria and methods

Students will be assessed on their understanding of the vector calculus, the equations of electrostatic field, the electric field distribution and electric field energy of the system including conductor and dielectric materials, and their ability to apply them to solve problems. Students' course scores are based on reports (to evaluate understanding level) at 2 times by zoom as well as on a face-to-face final exam (between June 2 and June 10) (about 70%), and homework (about 30%). The planned face-to-face exam will be shifted to other modes or methods if the spread of COVID-19 worsens.
