Norton’s Theorem Explained | Find IN & RN | GATE ECE Network Theory

Norton’s Theorem explained step by step for GATE ECE Network Theory. In this video, we learn how to find the Norton equivalent of a linear two-terminal circuit, including Norton current IN and Norton resistance RN. We then reconnect the load resistor and calculate the load current using the Norton equivalent. You’ll learn: • Norton’s Theorem • How to find Norton current IN • Short-circuit current ISC • How to find Norton resistance RN • Deactivation of independent sources • Norton equivalent circuit • Load current using current division • Relationship between Norton and Thevenin equivalents • Dependent sources and the test-source method Example covered: V1 = 1 V R1 = R2 = R3 = RL = 1 kΩ IN = 0.333 mA RN = 1.5 kΩ IL ≈ 0.2 mA This video is useful for GATE ECE aspirants preparing Network Theory and Circuit Analysis, as well as students learning Norton’s Theorem from the basics. In upcoming videos, we’ll solve GATE ECE previous-year questions based on Norton’s Theorem. #NortonsTheorem #GATEECE #NetworkTheory #CircuitAnalysis #GATE2027
