Superposition Theorem Example (Electric Circuits)

This video goes through an example, examining voltage across and current through resistors in a circuit with two voltage sources (10V and 12V). To analyze the circuit, the superposition theorem is used - the circuit is analyzed in two stages. The first stage involves turning the 12V source off and leaving the 10V source on. All the currents and voltages are determined with this (sub)circuit. The second stage involves turning the 10V source off and leaving the 12V source on. All the currents and voltages are determined with this (sub)circuit too. The results are then added together (e.g. voltage across R1 from stage 1 is added to voltage across R1 from stage 2) to give the results for the circuit as a whole 00:05 - The circuit to analyze 00:47 - Stage 1. 10V source on, 12V source off 2:40 - Voltage and current calculations for Stage 1 5:36 - Results from 10V on/12V off 6:11 - Stage 2. 12V source on, 10V source off 7:30 - Voltage and current calculations for Stage 1 10:26 - Results from 12V on/10V off 11:05 - Voltages and currents for initial circuit
