Let’s start with the basic definition of the transient behavior of the capacitor. The electrical behavior of a capacitor that does not have a constant voltage or current, also the variation in the current and voltage is not periodic and controlled, is referred to as the transient response or behavior of the capacitor.
The maximum discharge current occurs the instant the switch is thrown to position 2 when all of the capacitor's 12 volts drops across the 120 k Ω Ω resistor, yielding 100 μ μ amps, flowing top to bottom. Clearly, at t = 90 t = 90 milliseconds the capacitor is in the discharge phase.
The discharging capacitor is connected via a resistor to the rails, as shown on the left in Fig. 7.4. Resistor R models ohmic losses in the metal rails and a (typically small) series resistance of the capacitor. The capacitor current flows through two metal rails and through a sliding or rolling metal rod to be accelerated.
Charging is the inverse process of discharging a capacitor and it involves a power supply. The corresponding circuit is shown in Fig. 7.7. The switch closes at \ ( t=0 \). The resistor R can be either the Thévenin resistance of the practical voltage source or the series parasitic resistance of the capacitor itself or even a combination of both.
Discharging Behavior: When disconnected from the power source and short-circuited, a capacitor discharges, with the voltage and current decreasing exponentially to zero. Kirchhoff’s Laws in Capacitor Circuits: Kirchhoff’s Voltage Law helps determine the relationship between voltage and current in a capacitor during its transient response.
REVIEW: Capacitors act somewhat like secondary-cell batteries when faced with a sudden change in applied voltage: they initially react by producing a high current which tapers off over time. A fully discharged capacitor initially acts as a short circuit (current with no voltage drop) when faced with the sudden application of voltage.
