Lec 4 Series–Parallel Circuits | Electrical Engineering Foundation | One Law One Lecture

Описание: In this lecture of One Law One Lecture, we cover one of the most practical and frequently used topics in Electrical Engineering –
Series–Parallel Circuits along with the Current Division Rule (CDR) and Voltage Division Rule (VDR).

These concepts are used everywhere in circuit analysis and are essential for:

Network Analysis

Thevenin & Norton theorems

Load calculations

Power Systems basics

Instrumentation & Electronics circuits

🔹 Topics covered in this lecture:

What is a series circuit

What is a parallel circuit

How to identify hidden series–parallel connections

Equivalent resistance calculation

Voltage behavior in series circuits

Current behavior in parallel circuits

Voltage Division Rule (VDR) – concept & formula

Current Division Rule (CDR) – concept & formula

Common exam traps and mistakes

2–3 numericals for practical understanding

🔹 Why this lecture is important:

Almost every numerical starts with series–parallel reduction

Division rules save time in exams

Forms the base for:

Network theorems

AC circuit solving

Power & loss calculations

⚠️ Important Note
This is a free foundation lecture meant for strengthening basic concepts.
It does not include full-length problem practice, PYQs, test series, or complete exam strategy.
These are covered in our paid coaching programs.

👨‍🎓 Useful for:

AE / JE aspirants

PSU / State Electricity Board exam candidates

Engineering students (EE / ECE / Instrumentation)

Anyone learning basic circuit analysis

📌 Lecture Format:
Concept → Formula → Application → Numericals → Key Takeaways

📺 Language: Hindi
🎯 Focus: Conceptual clarity + exam orientation

One line to remember:

If you can reduce a circuit correctly, half the problem is already solved.
