Effect of capacitor size on output voltage of a rectifier circuit
Observations (using a 5 V peak AC signal input): If I leave the resistor fixed at 1 kΩ, and I used a 1 uF capacitor, I get a sawtooth shape graph (expected) with a decent sized ripple and the peak voltage of the ripple is 4.4 V. If I increased the capacitor size to 100 uF and leave the resistor fixed, I get a smoother (more DC-like) voltage.

Capacitor in an AC Circuit (Video)
A capacitor is charged by passing an electric current through it, which causes the plates to start accumulating an electrostatic charge. Since the strength of the charging current is maximum when the capacitor plates are uncharged and gradually decreases exponentially until the capacitor is fully charged, the charging process is neither instantaneous nor linear.

Consider the capacitor connected directly to an AC voltage source as shown in Figure 23.44. The resistance of a circuit like this can be made so small that it has a negligible effect compared with the capacitor, and so we can assume negligible resistance. Voltage across the capacitor and current are graphed as functions of time in the figure.
