Purpose of class
Understand transient phenomena underlying electrical circuits through differential equations.
Course description
[Summary]
In Electric Circuits 1 and 2, students learned about the analysis of sinusoidal AC voltage and current in steady states. When a DC or AC power source is connected to an electric circuit via a switch and the switch is turned on or off, the relationship between voltage and current behaves differently from steady-state conditions. This is called a transient phenomenon in an electric circuit. In this class, students will learn about electric circuits consisting of R, L, and C.
・What are transient phenomena?
・Representations of electric circuits using differential equations and their solutions.
[General Objectives]
Understand the behavior of electric circuits consisting of R, L, and C during transients and acquire the ability to quantitatively analyze them.
[Prerequisites] Completion of Electric Circuits 1 and 2 is required.
