About this course
Circuit analysis is the subject that turns two conservation laws into a complete method: Kirchhoff's current and voltage laws, applied carefully, are enough to solve any lumped network you will meet as a student. The difficulty is almost never the algebra — it is choosing the right method, getting the sign conventions right, and knowing which quantities are continuous at a switching instant. This course covers that ground as a sequence of practice questions rather than a lecture series. You answer, you find out immediately whether your reasoning held, and you move on.
What it covers
Twelve topics, working from conventions and resistive reduction through nodal and mesh formulation, the network theorems, capacitor and inductor behaviour, first-order and second-order transients, sinusoidal steady state and phasors, AC power and power factor, frequency response and resonance, and coupled circuits and two-port parameters. A final topic on choosing between methods asks the question exams actually ask: given this network, which approach is least work?
Who this is for
Electrical, electronics, and instrumentation students meeting the subject for the first time, and anyone revising it for GATE, a placement test, or a university exam. It assumes you can handle simultaneous equations and complex numbers in polar form. It does not assume you have seen a phasor diagram, a Thevenin equivalent, or a time constant before — the first topic starts at the passive sign convention and why the reference node you pick does not change the answer.
How MCQ practice works on Abekus
The course is organised as topics, subtopics, and individual lessons. Each lesson pairs a short set of explanation cards with practice questions written for that lesson, so the questions test the idea you just read rather than a general survey. Wrong answers come with a worked explanation, and the AI guide surfaces the mistakes you keep repeating — for this subject that is usually a sign convention or an initial condition, not the solving.
