Circuit Theory

Where this course goes deeper

Circuit Theory is a 51-lecture NPTEL course from IIT Delhi that sits one step beyond basic circuit analysis. It spends its time on how networks behave over time, starting with network equations and initial and final conditions, then step and impulse responses and second-order circuits with magnetically coupled elements.

The second half turns to network functions: how to read amplitude and phase from them, how poles and zeros shape a response, and how single tuned circuits behave. Several problem sessions run alongside the theory, so the course rewards anyone who actually works the problems.

Who should take it

• Electrical and electronics students who already know basic circuit laws
• Engineers who need to revisit transient and frequency-domain analysis

If you only want a quick refresher on Ohm's law, this will be more than you need.
