Скачать или смотреть 2.1 (d): Valid Electric Circuits – Electric Circuits by Nilsson (Voltage & Current Source Analysis)

🔌 Welcome back, engineers and circuit enthusiasts! 🚀 In this video, we tackle *Problem 2.1* part (d) from *Chapter 2* of **Electric Circuits by James W. Nilsson & Susan A. Riedel**, one of the most renowned textbooks in circuit analysis.

🎯 *What you'll learn in this video:*
• How to determine the validity of connecting ideal voltage and current sources in a loop after reversing the polarity of the original circuit
• Identifying which sources are delivering power and which are absorbing it
• Verifying power balance using real calculations
• Exploring the effect when reversing the polarity of a voltage source—and understanding why power still balances

📚 *Book Reference:*
Nilsson, J.W. & Riedel, S.A., *Electric Circuits*, 10th–12th editions (Pearson), widely used in engineering programs.

---

*Why You Should Watch:*
Nail your *circuit theory* homework with clarity
Understand essential concepts like *power analysis**, **source interconnection validity**, and **KVL/KCL* in a visual, step-by-step breakdown
Essential viewing for students in *Introductory Circuit Analysis**, **EE**, and **ECE* courses
