5.10: Exponential Charge Flow

The voltage across the capacitor for the circuit in Figure 5.10.3 starts at some initial value, (V_{C,0}), decreases exponential with a time constant of (tau=RC), and reaches zero when the capacitor is fully discharged. For the resistor, the voltage is initially (-V_{C,0}) and approaches zero as the capacitor discharges, always following the loop rule so the …

Example (PageIndex{1A}): Capacitance and Charge Stored in a Parallel-Plate Capacitor. What is the capacitance of an empty parallel-plate capacitor with metal plates that each have an area of (1.00, m^2), separated by 1.00 mm?

Understanding Capacitance and Electron Flow

We already established above that adding each new electron to the plate of a capacitor is slightly more difficult than the last. For a signal that changes rapidly from positive to negative voltage, electrons are being added to the capacitor plate for a brief period of time, and the sucked right back off again by the oscillating voltage.
