Can a capacitor charge and discharge at the same time?

No, the charge on a capacitor is increasing (charging), decreasing (discharging) or remaining the same. There are no other possible states (assuming an ideal capacitor with no leakage). When the capacitor is charging or discharging, there is a potential difference between the two terminals and apparent current flow.

23.2: Reactance, Inductive and Capacitive

Capacitors favor change, whereas inductors oppose change. Capacitors impede low frequencies the most, since low frequency allows them time to become charged and stop the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum.

Full-wave bridge rectifier with capacitor filter and ripple voltage

The voltage change on a capacitor from a current over time is: dV = A s / F. where: dV is the voltage change A the current in Amperes s the time in seconds F the capacitance in Farads. This pretty much tells you the peak to peak ripple, except that it is in terms of the time for the droop, not the frequency of the signal being rectified.

Ideal Capacitor. What is a Capacitor? A capacitor is a device that can store energy due to charge separation. In general, a capacitor (and thus, capacitance) is present when any two conducting surfaces are separated by a distance. A simple example is two parallel plates of shared cross-sectional area A separated by a distance d.

TRANSFORMERS – Applied Industrial Electricity

Since instantaneous winding voltage is proportional to the instantaneous magnetic flux''s rate of change in a transformer, a voltage waveform reaching the same peak value, but taking a longer amount of time to complete each half-cycle, demands that the flux maintain the same rate of change as before, but for longer periods of time. Thus, if ...
