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 …

Electric Fields and Capacitance | Capacitors | Electronics Textbook

Capacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it stores energy (current going in the positive side and out the negative side, like a resistor).

18.5 Capacitors and Dielectrics

For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by
