Superposition Theorem - Circuit Analysis Introduction + Solved Example

This tutorial demonstrates how to apply the Superposition Theorem to solve a circuit with two voltage sources. The video walks through a step-by-step example where the goal is to find the total current in a specific branch. You'll learn how to deactivate all but one independent source at a time, solve the resulting simpler circuits for partial currents, and then sum the contributions algebraically to find the final solution. The example covers key skills like circuit simplification (series/parallel combinations), Ohm's Law, and the Current Divider Rule. 00:00:00 - Introduction to the Superposition Theorem 00:01:49 - Problem Setup: Circuit with Two Voltage Sources 00:02:23 - Step 1: Analyze Circuit with First Source Active (10V Source) 00:03:19 - Simplify Circuit and Find Equivalent Resistance 00:05:49 - Calculate First Partial Current (I1_B) 00:07:24 - Use Current Divider Rule to Find Second Partial Current (I2_B) 00:12:38 - Step 2: Analyze Circuit with Second Source Active (20V Source) 00:15:27 - Simplify the Second Circuit Configuration 00:17:01 - Find Equivalent Resistance and Partial Current (I2_C) 00:18:48 - Apply Current Divider Rule Again for I1_C 00:20:48 - Step 3: Combine Results using Superposition 00:24:11 - Sum Partial Currents to Find Total Branch Current (I1 + I2) 00:27:53 - Final Result and Conclusion #SuperpositionTheorem #CircuitAnalysis #ElectricalEngineering #OhmsLaw #CurrentDivider #SeriesParallel #DCcircuits
