When the AC source is low frequency (50 Hz, 60 Hz, 120 Hz...) the capacitors are physically large, and could tolerate high ESR (like, 1 ohm for a 1A supply with a 1000 uF filter capacitor). That''s because a one-amp ripple current only created one watt of heat, and a large (over a square inch of surface area) 1000uF capacitor can shed that heat. - Download [PDF]

If a capacitor attaches across a voltage source that varies (or momentarily cuts off) over time, a capacitor can help even out the load with a charge that drops to 37 percent in one time constant. The inverse is true for charging; after one time constant, a capacitor is 63 percent charged, while after five time constants, a capacitor is considered fully charged.
This is an article showing a user how he can test a capacitor to see if it is good or defective. We go through several different tests, all using a multimeter.
