An electrical example of exponential decay is that of the discharge of a capacitor through a resistor. A capacitor stores charge, and the voltage V across the capacitor is proportional to the charge q stored, given by the relationship. V = q/C, where C is called the capacitance.
Battery charges capacitor to applied voltage. At the same time, the positive terminal attracts free electrons from plate B. The side of the dielectric at plate A accumulates electrons because they cannot flow through the insulator, and plate B has an equal surplus of protons.
Instead of the exponential dependence of charging and discharging voltages with time for a resistor-capacitor circuit, a linear time dependence is found when the resistor is replaced by a reverse-biased diode. Thus, well controlled positive
