Basic Electrical Circuits

A structured start

Basic Electrical Circuits is a 143-lecture NPTEL course from IIT Madras, and its length reflects how carefully it builds up. It begins with the vocabulary of the subject, current and voltage, then introduces the elements you meet in every circuit: resistors, capacitors, inductors and mutual inductors.

From there the course shows how these pieces connect. Kirchhoff's current and voltage laws come first, followed by voltage and current sources and series connections of R, L and C elements. The approach suits anyone who wants each concept to rest on the one before it.

Takeaways

• Clear definitions of the basic electrical quantities
• How real elements behave when they are wired together
• A foundation for later courses on AC and electronic circuits
