Capacitor Charge, Discharge and Time Constant Calculator
Circuits that have both resistive and capacitive elements (called RC circuits) take time to charge and discharge. During that time, the voltage across the capacitor is constantly changing. The calculator on this page will automatically determine the time constant, electric charge, time to fully charge or discharge, and the total voltage while charging or …
Charging and Discharging a Capacitor
When the capacitor begins to charge or discharge, current runs through the circuit. It follows logic that whether or not the capacitor is charging or discharging, when the plates begin to reach their equilibrium or zero, respectively, the current slows down to eventually become zero as well.
Basic Electronics
Basic Electronics - Capacitors - A Capacitor is a passive component that has the ability to store the energy in the form of potential difference between its plates. It resists a sudden change in voltage. The charge is stored in the form of potential difference between two plates, which form to be positive and negative depending upo

Capacitor Characteristics/Specifications
The dielectric absorption of a capacitor is the inability of a capacitor to completely discharge to zero. It is sometimes referred to battery action or capacitor memory, because of this charge retention, and this is due to the dielectric of the capacitor retaining a charge after it is supposedly discharged.
