Including capacitor charging and discharging direction
Capacitor Charging and Discharging
Just be sure that you insert the capacitor(s) in the proper direction: with the ends labeled negative (-) electrically "closest" to the battery''s negative terminal! The discharging circuit provides the same kind of changing capacitor voltage, except this time the voltage jumps to full battery voltage when the switch closes and slowly falls when the switch is opened.
The Fundamentals of Capacitors in AC Circuits
As with inductors, capacitors charge and discharge, and the energy stored in the capacitor in the one-quarter cycle is returned in the next quarter cycle, so the average power in a purely capacitive circuit is zero. In Figure 1, the shaded power waveform results from multiplying the instantaneous voltage and current values.

CHARGE AND DISCHARGE OF A CAPACITOR
CHARGE AND DISCHARGE OF A CAPACITOR Capacitor Discharging Figure 3. Capacitor Charging Figure 4. THE EXPONENTIAL The exponential voltage function, which is derived from equation (1), V(t) V (2) o e t-is shown in Figure 3. It has a slope (rate of
Can a capacitor charge and discharge at the same time?
Because the battery has capacitor characteristics so current (rate of charge flow) only flows in one direction at any time. Conductors are somewhat different. You can have impedance controlled frequencies sent in opposite directions called full duplex modems or as in telephones control voltage in one direction and current in the …

Charging. During the charging of a capacitor: the charging current decreases from an initial value of (frac {E} {R}) to zero. the potential difference across …
Charging and discharging a supercapacitor in molecular …
Supercapacitors have the unique ability to store much more energy than conventional capacitors and to charge and discharge much faster than batteries. ... The arrows indicate the directions of flow of positive charge carriers during discharging, from the positive electrode on the right to the negative electrode on the left, and from the ...
21.6 DC Circuits Containing Resistors and Capacitors
When you use a flash camera, it takes a few seconds to charge the capacitor that powers the flash. The light flash discharges the capacitor in a tiny fraction of a second. Why does charging take longer than discharging? This question and a number of other phenomena that involve charging and discharging capacitors are discussed in this module.

voltage
The capacitor discharge when the voltage drops from the main voltage level which it connected to like it connected between (5v and GND ) if voltage drops to 4.1v then the capacitor discharge some of its stored charge,the drop in voltage may caused by many effects like increase in a load current due to internal resistance of non-ideal source .
