SUMMARY
The discussion focuses on determining the Thevenin resistance (R) for calculating the time constant (τ) in electrical circuits. Participants confirm that to find R, one must short the voltage source and calculate the equivalent resistance using parallel resistance formulas. Specifically, the Thevenin resistance for the first circuit is calculated as 6kΩ in parallel with 3kΩ, while the second circuit yields a Thevenin resistance of 0.5kΩ in parallel with (2kΩ + 3kΩ). This method is essential for accurately solving time constant problems in circuit analysis.
