GATE ECE 1993 PYQ | Superposition Theorem | Power with Multiple Sources | Network Basics

📌 Problem: GATE ECE 1993 | Network Theory | Superposition Theorem 📂 Topic: Network Theorems | Subject: Networks (GATE ECE 2027) In this video, we solve the GATE ECE 1993 problem on Superposition Theorem where power dissipated in resistor R is 4W due to Source 1 alone and 9W due to Source 2 alone. We find the total power when BOTH sources are active. ⚠️ Key concept covered: → Superposition applies to VOLTAGE and CURRENT — NOT to power directly → Power is a nonlinear (quadratic) function of current/voltage → Correct approach: superpose currents first, then compute power → Common exam trap: directly adding individual powers (4+9 = 13W ❌) ✅ What you'll learn: Step-by-step application of Superposition Theorem Why P_total ≠ P1 + P2 in general How to avoid this classic GATE mistake #GATE2027 #GATENetworkTheory #SuperpositionTheorem #GATEECE #NetworkTheory #CircuitAnalysis #GATEPreviousYearProblems #ECE #GATE1993
