SUMMARY
The discussion focuses on the mathematical relationship between charge/discharge time in RC circuits and the values of resistors (R) and capacitors (C). The RC time constant, defined as τ = R × C, directly influences the time it takes for a capacitor to charge or discharge. As either the resistance or capacitance increases, the time required for the capacitor to reach approximately 63.2% of its final charge also increases. The irrational number e, approximately equal to 2.718, is integral to understanding this relationship, as it represents the base of natural logarithms used in calculating the time constant.
