SUMMARY
The discussion centers on the charging behavior of a 2.2μF capacitor connected to a 10kΩ resistor with a 10V supply. The time constant (T) is calculated as T = RC, resulting in T = 22 milliseconds. After three time constants, the voltage across the capacitor can be determined using the formula V(t) = V0(1 - e^(-t/T)), leading to a charge of approximately 9.5V after 66 milliseconds. This analysis utilizes fundamental principles of first-order linear differential equations.
