Course Description

The electric circuits are indispensable to understand electronics and to design electronic circuits.
Mathematical active models of resistance, coil and capacitor in electric circuits are understood. The issues of practice are solved in the lecture.In this lesson, students will acquire knowledge, techniques, and attitudes about DP4E while doing group work.
This lesson is related to DP4E

Course Objectives

It's important to analyze mathematically behavior of the electric physical quantity in the junction point of circuits.
It's the objectives to understand electric characteristics of the circuitry and to learn the mathematical analysis.
The objectives of the students in this lesson are to be able to follows: (1) Students learn basic theory of direct current circuit and Kirchhoff's law and theorems such as Thevenin's theorem.
(2) Students can explain phasor display and complex number display of sinusoidal alternating current.
(3) Students can calculate the impedance of the AC circuit.

Grading Policy

Students will be evaluated at 60% regular report and 40% report only if all reports are submitted.
Feedback and added explanations about points to be corrected when returning the report.
